For each finding below, click to specify if the finding is consistent with the disease process of chronic heart failure or chronic obstructive pulmonary disease. Each finding may support more than one disease process.
- A. Fatigue
- B. Dyspnea
- C. S3 heart tone
- D. Rapid weight gain
- E. Pink, frothy sputum
- F. Barrel-shaped chest
Correct Answer:
Rationale: Chronic heart failure (HF) is a progressive condition characterized by impaired ventricular function that leads to decreased
cardiac output and inadequate tissue perfusion as blood backs up into the lungs and systemic circulation. Common clinical
manifestations of HF include:
• Fatigue and dyspne secondary to impaired gas exchange
• An S3 (eg, ventricular gallop) heart tone, characteristic of HF, occurs during early diastole when blood from the atria
enters the ventricle and hits the less compliant (stiff) ventricular wall, creating an audible vibration
• Rapid weight gain (>5 lb/week [2.3 kg/week]) due to fluid volume overload
• Blood-tinged (ie, pink), frothy sputum due to mixing of blood from the ruptured high-pressured pulmonary veins with
transudative (clear alveolar fluid (pulmonary edema)
Chronic obstructive pulmonary disease (COPD) is a progressive, irreversible respiratory tract condition characterized by
chronic airway inflammation, alveolar destruction and enlargement, and/or increased mucus production. Clients with COPD
have the following:
• Fatigue and dyspnea related to impaired gas exchange
• Appearance of a barrel-shaped chest due to the increased anteroposterior-to-transverse diameter ratio from
hyperinflation of the lungs

Select 5 findings that require immediate follow-up.
- A. SpO, 92% via nonrebreather mask
- B. unilateral chest wall expansion observed on
inspiration - C. left-sided tracheal deviation noted;
- D. breath sounds diminished throughout the right lung
field - E. Superficial lacerations to the face
- F. BP 90/58; S1 and S2 heard on auscultation; all pulses palpabl
Correct Answer: A,B,C,D,F
Rationale: The nurse should immediately follow up on the following findings:
• Hypoxemia (eg, SpO, 92% on 100% oxygen [nonrebreather mask]) indicates an abnormality with ventilation and/or perfusion.
• Unilateral chest wall expansion on inspiration indicates one side of the lung is not inflating. This is usually due to lung collapse,
which could be due to an internal airway dysfunction (eg, mucous plug blocking air entry) or external compression (eg, pneumothorax).
• Tracheal deviation (ie, displacement of the trachea to one side) occurs when pressure from one side of the chest is higher than the
other, pushing the mediastinal structures to the side with less pressure. This is usually due to a large hemothorax or pneumothorax.
• Diminished breath sounds indicate the lung is not adequately expanding (eg, atelectasis, pneumothorax).
• Hypotension (eg, BP 90/58 mm Hg) occurs from several mechanisms, including compression of the heart (eg, cardiac tamponade)
and/or great vessels (eg, tension pneumothorax), inadequate ventricular filling between heartbeats (eg, supraventricular tachycardia),
volume depletion, and other conditions
For each potential intervention, click to specify if the intervention is expected or not expected for the care of the client.
- A. Daily weights
- B. IV furosemide
- C. Fluid restriction
- D. Supplemental oxygen
- E. Antihypertensive medications
- F. Nebulized albuterol breathing treatments
Correct Answer:
Rationale: Expected interventions for acute decompensated heart failure (HF) focus on reducing cardiac workload and improving
oxygenation. These include:
• Daily weights should be performed to monitor fluid volume status and guide treatment. Ideally, daily weights should be
performed at the same time of day, on the same scale, and with the client wearing the same amount of clothing.
• Diuretics (eg, furosemide) prevent reabsorption of sodium and chloride in the kidneys, which increases fluid excretion in
urine and decreases preload. Diuretics provide symptomatic relief by reducing pulmonary congestion and peripheral
edema. These are the cornerstone of therapy and often a priority after oxygen therapy.
• Fluid restriction is indicated to decrease circulating fluid volume and prevent excess strain on the heart.
• Supplemental oxygen should be administered to improve oxygen delivery in clients with HF due to impaired gas
exchange from pulmonary edema.
• Antihypertensive medications reduce cardiac workload and improve contractility by lowering blood pressure (ie,
afterload).
Nebulized albuterol is a bronchodilator administered to improve oxygenation in clients with reactive airway disease (eg.
asthma, chronic obstructive pulmonary disease). Bronchodilators will not improve oxygenation in clients with pulmonary
edema and are not expected for treatment of HF.
Which of the following findings are consistent with a tension pneumothorax? Select all that apply.
- A. Diminished breath sounds on one side
- B. Dyspnea
- C. Hypotension
- D. Recent thoracic trauma
- E. Tracheal deviation
- F. Unilateral chest wall expansion
Correct Answer: A,B,C,D,E,F
Rationale: A pneumothorax is characterized by air inside the pleural space, which disrupts the negative pressure that maintains lung expansion. This
causes the lung to collapse either partially or completely, leading to unilateral, diminished breath sounds; unilateral chest wall
expansion; and dyspnea. A pneumothorax often occurs from blunt thoracic trauma (eg, during a motor vehicle collision). Air can also ent
the pleural space through the chest wall and parietal pleura (open pneumothorax) during or after an invasive procedure on or near the chest
wall (eg, thoracentesis, paracentesis, central line insertion) (Options 1, 2, 4, and 6).
Select 5 findings that require immediate follow-up.
- A. left-sided headache
- B. Bilateral lens opacity
- C. 7.9-Ib (3.6-kg) weight loss within the past month.
- D. blurred vision and redness in the left eye
- E. severe pain in the left eye
- F. red conjunctiva.
- G. Left eye: pupil 4 mm and nonreactive to light
Correct Answer: A,D,E,F,G
Rationale: This client is experiencing signs of acute angle-closure glaucoma (ACG), a medical emergency characterized by a sudden elevation in
intraocular pressure (IOP). The onset of symptoms is typically sudden; however, acute ACG requires rapid intervention to prevent permane
vision loss. Manifestations of acute ACG include:
• Blurry vision
• Unilateral headache
• Sudden, severe eye pain
• Conjunctival redness
• Middilated pupils (4-6 mm) nonreactive to light
The nurse reinforces discharge teaching to the client after laser peripheral iridotomy. Which of the following client statements indicate an understanding of the teaching? Select all that apply.
- A. Gently pulling down my lower eyelid creates a pocket where I should administer the drops.
- B. I will apply pressure over the inner corner of my eye after administering each medication
- C. I will stop taking diphenhydramine because it can cause a glaucoma attack.
- D. I will wait 5 minutes between administering each eye drop medication.
- E. Touching my eye with the medication applicator may cause an infection.
Correct Answer: A,B,C,D,E
Rationale: Laser peripheral iridotomy is a surgical intervention for acute angle-closure glaucoma (ACG) that involves creating a small hole in the iris to
prevent the drainage pathway from closing and improve movement of aqueous humor into regular outflow channels. Ophthalmic alpha-
adrenergic agonists (eg, apraclonidine, brimonidine) are administered postoperatively to reduce aqueous humor production and prevent an
elevation in intraocular pressure.
Important considerations for the administration of ophthalmic drops include:
• Pulling the lower eyelid down by gently pressing on the lower orbital bone to expose the conjunctival sac (Option 1)
• Applying pressure over the inner corner of the eye (eg, lacrimal duct) after each medication to avoid systemic absorption (Option 2)
• Waiting at least 5 minutes before instilling a different medication into the same eye to allow absorption of the first medication and to
avoid overflow with multiple drops (Option 4)
• Holding the dropper ½*% in (1-2 cm) above the conjunctival sac to prevent contamination of the dropper and infection of the eye
(Option 5)
Clients should also be instructed to consult with their health care provider before taking over-the-counter medications (eg, decongestants,
anticholinergics, antihistamines) because a subsequent episode of acute ACG may be triggered by certain medications (Option 3).
