The healthcare professional counts an adult's apical heartbeat at 110 beats per minute. The healthcare professional describes this as:
- A. Asystole
- B. Bigeminy
- C. Tachycardia
- D. Bradycardia
Correct Answer: C
Rationale: Tachycardia is a heart rate greater than 100 beats per minute. In this case, an adult's heart rate of 110 beats per minute falls within the range of tachycardia. Tachycardia can be a common physiological response to various stresses on the body, leading to an increased heart rate. Asystole refers to the absence of cardiac activity, bigeminy is a specific heart rhythm pattern, and bradycardia is a heart rate below 60 beats per minute in adults.

Following a craniotomy, why did the nurse position the client in low Fowler's position?
- A. To promote comfort.
- B. To promote drainage from the operation site.
- C. To promote thoracic expansion.
- D. To prevent circulatory overload.
Correct Answer: B
Rationale: Positioning the client in low Fowler's position after a craniotomy is essential to promote drainage from the operation site. This position helps prevent fluid accumulation, facilitates the removal of excess fluid or blood, and aids in the healing process. Choice A is incorrect because comfort, while important, is not the primary reason for this specific positioning. Choice C is incorrect as thoracic expansion is not the main concern following a craniotomy. Choice D is incorrect as circulatory overload is not typically addressed by positioning in low Fowler's position post-craniotomy.
Which instruction is most important for the nurse to include when teaching a client with limited mobility strategies to prevent venous thrombosis?
- A. Perform cough and deep breathing exercises hourly.
- B. Turn from side to side in bed at least every 2 hours.
- C. Dorsiflex and plantarflex the feet 10 times each hour.
- D. Drink approximately 4 ounces of water every hour.
Correct Answer: C
Rationale: The most crucial instruction for a client with limited mobility to prevent venous thrombosis is to perform dorsiflexion and plantarflexion of the feet 10 times each hour. These exercises help promote venous return, reducing the risk of thrombosis by preventing blood stasis in the lower extremities. While other measures like turning in bed and staying hydrated are beneficial, promoting venous return through foot exercises is the priority in preventing venous thrombosis in clients with limited mobility. Dorsiflexion and plantarflexion directly target the calf muscle pump, aiding in the circulation of blood back to the heart and preventing clot formation. The other options, such as cough and deep breathing exercises, turning in bed, and hydration, are important for overall health but do not directly address venous stasis and thrombosis prevention in the same way as foot exercises.
The client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which intervention should the nurse implement to ensure the client's safety?
- A. Encourage the client to use oxygen continuously
- B. Monitor the client's respiratory rate and effort
- C. Set the oxygen flow rate at 6 liters per minute
- D. Teach the client to avoid wearing wool blankets
Correct Answer: B
Rationale: Monitoring the client's respiratory rate and effort is essential to evaluate the effectiveness of oxygen therapy and prevent complications such as respiratory depression. This intervention helps the nurse promptly detect any deterioration in the client's respiratory status and take necessary actions to ensure the client's safety. Encouraging continuous oxygen use (Choice A) may lead to oxygen toxicity. Setting the oxygen flow rate at a specific level (Choice C) without individual assessment can be inappropriate and potentially harmful. Teaching the client to avoid wearing wool blankets (Choice D) is unrelated to the safe use of oxygen therapy.
When assessing for orthostatic hypotension during blood pressure measurement, what action should the nurse implement first?
- A. Position the client supine for a few minutes
- B. Assist the client to stand at the bedside
- C. Apply the blood pressure cuff securely
- D. Record the client's pulse rate and rhythm
Correct Answer: A
Rationale: When assessing for orthostatic hypotension, the initial step is to position the client supine for a few minutes. This allows the body to adjust to the supine position before assessing blood pressure changes that may indicate orthostatic hypotension. By observing the blood pressure after the client has rested supine, the nurse can accurately assess for any drop in blood pressure upon standing, which is indicative of orthostatic hypotension. Choices B, C, and D are incorrect as they do not address the initial step in assessing for orthostatic hypotension, which is ensuring the client is positioned correctly to detect blood pressure changes upon standing.
When caring for an immobile client, what nursing diagnosis has the highest priority?
- A. Risk for fluid volume deficit.
- B. Impaired gas exchange.
- C. Risk for impaired skin integrity.
- D. Altered tissue perfusion.
Correct Answer: B
Rationale: When caring for an immobile client, the nursing diagnosis with the highest priority is impaired gas exchange. This is because impaired gas exchange implies difficulty with breathing, which is essential for sustaining life. Adequate oxygenation is crucial for all bodily functions, and any impairment in gas exchange can lead to serious complications, making it the priority nursing diagnosis to address in an immobile client. Choices A, C, and D are important considerations as well when caring for an immobile client, but they are secondary to impaired gas exchange. Risk for fluid volume deficit may occur due to immobility, but ensuring proper gas exchange takes precedence as it directly impacts the client's immediate survival. Risk for impaired skin integrity is a concern in immobile clients but does not pose an immediate threat to life like impaired gas exchange. Altered tissue perfusion is also critical but is usually a consequence of impaired gas exchange, reinforcing the priority of addressing gas exchange first.
