Nursing Elites

1. A nurse is caring for a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min, and the PR interval is 0.24 seconds. What cardiac rhythm should the nurse interpret this finding as?

• A. First-degree AV block.
• B. Premature ventricular contraction.
• C. Sinus bradycardia.
• D. Atrial fibrillation.

Correct answer: A

Rationale: The correct answer is A: First-degree AV block. A PR interval of 0.24 seconds indicates a prolonged PR interval, which is characteristic of first-degree AV block. This rhythm is considered benign and often does not require treatment. Choice B, premature ventricular contraction, is characterized by early, abnormal ventricular contractions and would not be indicated by the findings provided. Choice C, sinus bradycardia, would present with a normal PR interval but a heart rate less than 60 beats per minute. Choice D, atrial fibrillation, is characterized by an irregularly irregular rhythm with no identifiable P waves, which does not align with the findings of a prolonged PR interval in this scenario.

2. A client is being assessed in the PACU. Which of the following findings indicates decreased cardiac output?

• A. Shivering
• B. Oliguria
• C. Bradypnea
• D. Constricted pupils

Correct answer: B

Rationale: Oliguria is a sign of decreased cardiac output. Decreased cardiac output can lead to poor renal perfusion, resulting in decreased urine output (oliguria). This requires immediate intervention to improve cardiac function and perfusion. Shivering (Choice A) is a response to cold stress and does not directly indicate decreased cardiac output. Bradypnea (Choice C) refers to abnormally slow breathing rate and is more indicative of respiratory issues rather than decreased cardiac output. Constricted pupils (Choice D) are associated with the parasympathetic nervous system response and not directly related to cardiac output.

3. A nurse is preparing to insert an indwelling urinary catheter for a client. Which of the following actions should the nurse take?

• A. Insert the catheter 7.5 cm (3 in) into the urethra.
• B. Insert the catheter until urine flow is established.
• C. Cleanse the catheter with sterile water before insertion.
• D. Insert the catheter 5 cm (2 in) into the urethra.

Correct answer: B

Rationale: The correct action for the nurse is to insert the catheter until urine flow is established. This helps ensure proper placement and reduces the risk of trauma. Choice A (7.5 cm) and Choice D (5 cm) provide specific measurements that may not be appropriate for all individuals as catheter insertion depth can vary. Choice C is incorrect as catheters should be cleansed with an appropriate solution such as sterile saline, not sterile water.

4. A nurse is assessing a client who has chronic obstructive pulmonary disease (COPD). Which of the following findings should the nurse report to the provider?

• A. Oxygen saturation of 91%
• B. Use of pursed-lip breathing
• C. Productive cough with green sputum
• D. Decreased breath sounds in the right lower lobe

Correct answer: D

Rationale: The correct finding the nurse should report to the provider is decreased breath sounds in the right lower lobe. This can indicate a respiratory infection or atelectasis in clients with COPD, requiring further evaluation and intervention. Choice A, an oxygen saturation of 91%, although slightly lower than normal, does not necessarily require immediate reporting unless the client's baseline is significantly higher. Choice B, the use of pursed-lip breathing, is actually a beneficial technique for clients with COPD to improve oxygenation and reduce shortness of breath, so it does not need reporting. Choice C, a productive cough with green sputum, can be common in clients with COPD and may indicate an infection, but it is not as concerning as decreased breath sounds in a specific lung lobe which may signify a more acute issue.

5. A client has a new diagnosis of COPD. Which of the following instructions should the nurse include in the teaching?

• A. Breathe rapidly through your mouth when using the incentive spirometer.
• B. Use pursed-lip breathing during periods of dyspnea.
• C. Avoid drinking fluids during meals.
• D. Use diaphragmatic breathing during periods of dyspnea.

Correct answer: B

Rationale: Pursed-lip breathing is a beneficial technique for clients with COPD as it helps control shortness of breath and improves oxygenation. This technique involves inhaling slowly through the nose and exhaling through pursed lips, which helps keep airways open. Option A is incorrect as breathing rapidly through the mouth when using the incentive spirometer can lead to hyperventilation. Option C is incorrect because it is important for clients with COPD to stay hydrated by drinking fluids between meals, but not during meals which can cause bloating and discomfort. Option D is incorrect as diaphragmatic breathing, though beneficial, is not the preferred technique for managing dyspnea in COPD; pursed-lip breathing is more effective.
