In a patient with asthma, which of the following is the most important indicator of respiratory function?
- A. Oxygen saturation.
- B. Respiratory rate.
- C. Arterial blood gases.
- D. Peak expiratory flow rate.
Correct Answer: D
Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.

Which of the following is a priority intervention for a patient with heart failure?
- A. Administering diuretics.
- B. Administering oxygen.
- C. Administering beta-blockers.
- D. Administering vasodilators.
Correct Answer: B
Rationale: Administering oxygen is a priority intervention in heart failure because it helps improve oxygenation, alleviate hypoxemia, and reduce the workload on the heart. Oxygen therapy is crucial in managing acute heart failure exacerbations. While diuretics (Choice A) are commonly used in heart failure to reduce fluid overload, administering oxygen takes precedence due to its immediate impact on oxygen delivery. Beta-blockers (Choice C) and vasodilators (Choice D) are also important in heart failure management, but in the acute setting, ensuring adequate oxygen supply is the priority.
What is the primary nursing intervention for a patient experiencing an acute asthma attack?
- A. Administering bronchodilators.
- B. Administering antibiotics.
- C. Administering IV fluids.
- D. Administering corticosteroids.
Correct Answer: A
Rationale: The correct answer is administering bronchodilators. During an acute asthma attack, the primary goal is to relieve airway constriction and bronchospasm to improve breathing. Bronchodilators, such as short-acting beta-agonists, are the cornerstone of treatment as they help dilate the airways quickly. Administering antibiotics (choice B) is not indicated unless there is an underlying bacterial infection. Administering IV fluids (choice C) may be necessary in some cases, but it is not the primary intervention for an acute asthma attack. Administering corticosteroids (choice D) is often used as an adjunct therapy to reduce airway inflammation, but it is not the primary intervention during the acute phase of an asthma attack.
In a patient with anemia, which of the following is the primary symptom to assess?
- A. Fever.
- B. Chest pain.
- C. Shortness of breath.
- D. Muscle cramps.
Correct Answer: C
Rationale: The correct answer is C: Shortness of breath. In a patient with anemia, the primary symptom to assess is shortness of breath. Anemia leads to a reduced oxygen-carrying capacity of the blood, resulting in tissues not receiving adequate oxygen. This can manifest as shortness of breath, especially during physical exertion. Fever (Choice A), chest pain (Choice B), and muscle cramps (Choice D) are not typically primary symptoms of anemia. Fever may suggest an infection, chest pain can be indicative of cardiac issues, and muscle cramps may be related to electrolyte imbalances or neuromuscular disorders.
A client has had a pulmonary artery catheter inserted. In performing hemodynamic monitoring with the catheter, the nurse will wedge the catheter to gain information about which of the following?
- A. Cardiac output.
- B. Right atrial blood flow.
- C. Left end-diastolic pressure.
- D. Cardiac index.
Correct Answer: C
Rationale: The correct answer is C: Left end-diastolic pressure. Wedging the pulmonary artery catheter allows the nurse to obtain the pulmonary artery wedge pressure, which reflects the left end-diastolic pressure. This pressure is essential in assessing left ventricular function and diagnosing conditions like heart failure. Choices A, B, and D are incorrect because wedging the catheter does not directly provide information about cardiac output, right atrial blood flow, or cardiac index.
To assess the quality of an adult client's pain, what approach should the nurse use?
- A. Observe body language and movement.
- B. Ask the client to describe the pain.
- C. Identify effective pain relief measures.
- D. Provide a numeric pain scale.
Correct Answer: B
Rationale: The correct answer is to ask the client to describe the pain. This approach allows the nurse to gather subjective information directly from the client, such as the quality, intensity, location, and factors that aggravate or alleviate the pain. Observing body language and movement (Choice A) can provide additional cues but may not fully capture the client's pain experience. Identifying effective pain relief measures (Choice C) and providing a numeric pain scale (Choice D) are important aspects of pain management but do not directly assess the quality of the client's pain.
