Dr. Jones prescribes albuterol sulfate (Proventil) for a patient with newly diagnosed asthma. When teaching the patient about this drug, the nurse should explain that it may cause:40:40H272:382:422:412:402:422:402:38
- A. Nasal congestion
- B. Nervousness
- C. Lethargy
- D. Hyperkalemia
Correct Answer: B
Rationale: The correct answer is B: Nervousness. Albuterol sulfate is a bronchodilator commonly used to treat asthma. It works by relaxing the muscles in the airways, making it easier to breathe. Nervousness is a common side effect of albuterol due to its stimulant properties. Nasal congestion (Choice A) is not a typical side effect of albuterol. Lethargy (Choice C) is also not a common side effect, as albuterol typically has a stimulating effect. Hyperkalemia (Choice D) is not associated with albuterol use.

A nurse is providing care after auscultating a client's breath sounds. Which assessment finding is correctly matched to the nurse's primary intervention?
- A. Hollow sounds are heard over the trachea. The nurse increases the oxygen flow rate.
- B. Crackles are heard in bases. The nurse encourages the client to cough forcefully.
- C. Wheezes are heard in central areas. The nurse administers an inhaled bronchodilator.
- D. Vesicular sounds are heard over the periphery. The nurse has the client breathe deeply.
Correct Answer: C
Rationale: The correct answer is C because wheezes indicate narrowing of airways, requiring bronchodilation. Step 1: Identify the assessment finding (wheezes). Step 2: Understand that wheezes indicate airway constriction. Step 3: Appropriately intervene by administering a bronchodilator to dilate the airways and improve breathing. Other choices are incorrect because: A: Increasing oxygen flow rate does not address airway constriction. B: Encouraging coughing for crackles does not address airway narrowing. D: Deep breathing for vesicular sounds does not target airway constriction.
A male client with chronic obstructive pulmonary disease (COPD) is recovering from a myocardial infarction. Because the client is extremely weak and can't produce an effective cough, the nurse should monitor closely for:
- A. Pleural effusion
- B. Pulmonary edema
- C. Atelectasis
- D. Oxygen toxicity
Correct Answer: C
Rationale: The correct answer is C: Atelectasis. In a client with COPD recovering from a myocardial infarction, the weakened state and ineffective cough can lead to the collapse of alveoli, causing atelectasis. This condition can further impair gas exchange and oxygenation, leading to respiratory distress. Monitoring for atelectasis is crucial to prevent complications. Pleural effusion (A) and pulmonary edema (B) are not directly related to the client's condition and symptoms. Oxygen toxicity (D) is a potential concern with high oxygen therapy but is not the most immediate risk for this client scenario.
What is the term used to describe the fluid buildup in the lungs often seen in heart failure patients?
- A. Ascites
- B. Edema
- C. Pleurisy
- D. Effusion
Correct Answer: B
Rationale: The correct answer is B: Edema. In heart failure patients, fluid buildup in the lungs is known as pulmonary edema. This occurs due to the heart's inability to pump effectively, leading to fluid leaking into the lungs' air sacs. Ascites (A) is fluid buildup in the abdomen, not the lungs. Pleurisy (C) is inflammation of the lining around the lungs, not fluid buildup. Effusion (D) refers to fluid accumulation in body cavities like the chest or abdomen, but it is not specific to the lungs like pulmonary edema.
The partial pressure of oxygen in the interstitial space of peripheral tissues is approximately
- A. 40 mm Hg
- B. 45 mm Hg
- C. 50 mm Hg
- D. 70 mm Hg
Correct Answer: A
Rationale: The correct answer is A: 40 mm Hg. In peripheral tissues, oxygen is delivered by the blood through capillaries. The partial pressure of oxygen in the interstitial space of peripheral tissues is lower than in the blood, around 40 mm Hg. This allows for the diffusion of oxygen from capillaries to cells. Choice B (45 mm Hg) and C (50 mm Hg) are slightly higher pressures and would not promote efficient oxygen diffusion. Choice D (70 mm Hg) is closer to arterial blood oxygen levels and would not allow sufficient oxygen release to tissues. Thus, the correct answer is A as it reflects the physiological conditions necessary for effective oxygen delivery to cells.
cochlea's have how many fluid filled chamber?
- A. 1
- B. 2
- C. 3
- D. 4
Correct Answer: C
Rationale: The cochlea has 3 fluid-filled chambers: the scala vestibuli, scala media, and scala tympani. These chambers are essential for hearing as they contain different fluids (perilymph and endolymph) that help transmit sound vibrations. Choice A (1 chamber) is incorrect as the cochlea has multiple distinct chambers. Choice B (2 chambers) is incorrect as it does not accurately reflect the anatomical structure of the cochlea. Choice D (4 chambers) is incorrect as the cochlea typically consists of 3 chambers, not 4. Therefore, the correct answer is C (3 chambers) based on the accurate anatomical structure of the cochlea.
