The nurse administers prescribed therapies for a patient with cor pulmonale and right-sided heart failure. Which assessment would best evaluate the effectiveness of the therapies?
- A. Observe for distended neck veins.
- B. Auscultate for crackles in the lungs.
- C. Palpate for heaves or thrills over the heart.
- D. Review hemoglobin and hematocrit values.
Correct Answer: A
Rationale: To evaluate the effectiveness of therapies for cor pulmonale and right-sided heart failure, observing for distended neck veins would be the most appropriate assessment. Cor pulmonale is characterized by right ventricular failure due to pulmonary hypertension, leading to clinical manifestations such as peripheral edema, jugular venous distention, and right upper-quadrant abdominal tenderness. These signs indicate increased central venous pressure and right heart strain, which can be assessed by observing for distended neck veins. Auscultating for crackles in the lungs is more indicative of left-sided heart failure rather than right-sided heart failure. Heaves or thrills over the heart are not typically associated with cor pulmonale. Reviewing hemoglobin and hematocrit values may show elevations due to chronic hypoxemia and polycythemia in cor pulmonale, but these values alone do not directly evaluate the immediate effectiveness of the prescribed therapies on the patient's condition.

Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:
- A. It results when oxygen demand is greater than oxygen supply.
- B. It is characterized by pain that often occurs during rest.
- C. It is a result of tissue hypoxia.
- D. It is characterized by cramping and weakness.
Correct Answer: D
Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.
When caring for a patient hospitalized with active tuberculosis (TB), the nurse observes a student nurse who is assigned to take care of the patient. Which action, if performed by the student nurse, would require an intervention by the nurse?
- A. The patient is offered a tissue from the box at the bedside.
- B. A surgical face mask is applied before visiting the patient.
- C. A snack is brought to the patient from the unit refrigerator.
- D. Hand washing is performed before entering the patient's room.
Correct Answer: B
Rationale: When caring for a patient with active tuberculosis (TB), it is crucial to use a high-efficiency particulate-absorbing (HEPA) mask instead of a standard surgical mask when entering the patient's room, as a HEPA mask can filter out 100% of small airborne particles, reducing the risk of transmission. Therefore, if the student nurse applies only a surgical face mask before visiting the patient, this action would require intervention by the nurse to ensure the appropriate protective equipment is used. Hand washing before entering the patient's room is essential to prevent the spread of infection and is a correct action. Bringing a snack to the patient from the unit refrigerator is appropriate and helps address potential issues with anorexia and weight loss in patients with TB. While hand washing after handling a tissue used by the patient is necessary, no special precautions are required when offering the patient an unused tissue.
A patient is diagnosed with both human immunodeficiency virus (HIV) and active tuberculosis (TB) disease. Which information obtained by the nurse is most important to communicate to the healthcare provider?
- A. The Mantoux test induration measured 7 mm.
- B. The chest x-ray revealed infiltrates in the lower lobes.
- C. The patient is receiving antiretroviral therapy for HIV infection.
- D. The patient has a cough producing blood-tinged mucus.
Correct Answer: C
Rationale: The most critical information to communicate to the healthcare provider in a patient diagnosed with both HIV and active TB disease is that the patient is receiving antiretroviral therapy for HIV infection. This is crucial because drug interactions can occur between antiretrovirals used to treat HIV infection and medications used to treat TB. By informing the healthcare provider about the antiretroviral therapy, potential interactions can be assessed and managed effectively to optimize patient care. The other data provided, such as the Mantoux test result, chest x-ray findings, and presence of blood-tinged mucus, are important clinical information but are expected in a patient with coexisting HIV and TB and do not directly impact potential drug interactions between antiretrovirals and TB medications.
The nurse assesses a patient with chronic obstructive pulmonary disease (COPD) who has been admitted with increasing dyspnea over the last 3 days. Which finding is most important for the nurse to report to the healthcare provider?
- A. Respirations are 36 breaths/minute.
- B. Anterior-posterior chest ratio is 1:1.
- C. Lung expansion is decreased bilaterally.
- D. Hyperresonance to percussion is present.
Correct Answer: A
Rationale: The correct answer is 'Respirations are 36 breaths/minute.' An increased respiratory rate is a crucial sign of respiratory distress in patients with COPD, necessitating immediate interventions like oxygen therapy or medications. The other options are common chronic changes seen in COPD patients. Option B, the 'Anterior-posterior chest ratio is 1:1,' is related to the barrel chest commonly seen in COPD due to hyperinflation. Option C, 'Lung expansion is decreased bilaterally,' is expected in COPD due to air trapping. Option D, 'Hyperresonance to percussion is present,' is typical in COPD patients with increased lung volume and air trapping.
A 64-year-old patient with amyotrophic lateral sclerosis (ALS) is hospitalized with pneumonia. Which nursing action will be included in the plan of care?
- A. Assist with active range of motion (ROM).
- B. Observe for agitation and paranoia.
- C. Give muscle relaxants as needed to reduce spasms.
- D. Use simple words and phrases to explain procedures.
Correct Answer: A
Rationale: In a patient with ALS, progressive muscle weakness is a significant issue. Assisting with active range of motion (ROM) exercises will help maintain muscle strength for as long as possible. Agitation and paranoia are not typically associated with ALS, making choice B incorrect. Giving muscle relaxants can further weaken muscles and depress respirations, worsening the condition, so choice C is inappropriate. Choice D is not directly related to the patient's physical condition and needs.
