Nursing Elites

1. A client is scheduled for a spiral CT scan with contrast to evaluate for pulmonary embolism. Which information in the client's history requires follow-up by the nurse?

• A. Is allergic to shellfish
• B. Has a history of smoking
• C. Takes metformin for type 2 diabetes mellitus
• D. Has hypertension controlled with medication

Correct answer: A

Rationale: An allergy to shellfish often indicates an allergy to iodine, which is used in contrast dyes for CT scans. This poses a significant risk of an allergic reaction during the procedure. The nurse must ensure appropriate precautions or alternative imaging are considered. Choices B, C, and D are not directly contraindicated for a CT scan with contrast. Smoking history, metformin use, and controlled hypertension do not typically impact the safety or feasibility of the procedure.

2. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving oxygen therapy. Which assessment finding indicates that the client's oxygenation is improving?

• A. Pulse oximetry reading of 94%
• B. Heart rate increases from 80 to 90 beats per minute
• C. Respiratory rate increases from 16 to 20 breaths per minute
• D. Client reports increased energy levels

Correct answer: A

Rationale: A pulse oximetry reading of 94% indicates adequate oxygenation. Monitoring oxygen saturation is the most objective way to assess the effectiveness of oxygen therapy. Choices B, C, and D do not directly reflect the client's oxygenation status. An increase in heart rate or respiratory rate may indicate increased work of breathing or stress on the body. The client reporting increased energy levels is subjective and may not directly correlate with improved oxygenation.

3. A client with adrenal insufficiency is admitted to the ICU with acute adrenal crisis. The client's vital signs include heart rate 138 bpm and BP 80/60. What is the nurse's first intervention?

• A. Obtain an analgesic prescription.
• B. Administer an IV fluid bolus.
• C. Administer PRN antipyretic.
• D. Cover the client with a cooling blanket.

Correct answer: B

Rationale: The correct first intervention for a client with adrenal crisis and hypotension is to administer an IV fluid bolus. In adrenal crisis, the body is deficient in cortisol, leading to hypotension. Fluid resuscitation helps stabilize the blood pressure. Obtaining an analgesic prescription (Choice A) is not the priority in this situation. Administering a PRN antipyretic (Choice C) is not indicated as the client's vital signs do not suggest fever. Covering the client with a cooling blanket (Choice D) is not appropriate for addressing hypotension in adrenal crisis.

4. The nurse is caring for a client with an indwelling urinary catheter. Which of the following actions should the nurse prioritize to prevent infection?

• A. Maintain a closed drainage system
• B. Cleanse the catheter insertion site daily
• C. Increase the client's fluid intake
• D. Empty the collection bag every 4 hours

Correct answer: A

Rationale: The correct answer is to maintain a closed drainage system. This action is crucial in preventing infection as it helps prevent bacteria from entering the urinary tract. While cleansing the catheter insertion site and ensuring adequate hydration are important aspects of catheter care, the top priority is maintaining the integrity of the closed system to prevent infection. Emptying the collection bag regularly is also important but not as critical as ensuring a closed drainage system to minimize infection risk.

5. The nurse is teaching a client with asthma to use a peak expiratory flow rate (PEFR) meter to manage asthma at home. The nurse knows the client understands the proper use of the meter when the client:

• A. Inhales as rapidly as possible when using the meter
• B. Records the highest of three readings
• C. Uses the meter after taking a bronchodilator
• D. Blows out forcefully into the meter after taking a deep breath

Correct answer: B

Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.
