1. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?

• A. The body can produce sufficient amounts of vitamin D from sunlight.
• B. UV radiation can convert a precursor of vitamin D to vitamin D3 by penetrating uncovered skin.
• C. Sunscreen blocks the formation of vitamin D3.
• D. By the age of 70 years, the skin generally produces vitamin D at only half the level it did at the age of 20 years.

Correct answer: C

Rationale: While UV radiation can penetrate uncovered skin and convert a precursor of vitamin D to vitamin D3, sunscreen does block the formation of vitamin D3. Sunscreen is recommended by dermatologists to prevent sunburn and reduce the risk of skin cancer. The other choices are correct: the body can produce sufficient vitamin D from sunlight, UV radiation can convert a precursor of vitamin D to vitamin D3, and skin generally produces less vitamin D as a person ages.

2. A nurse is reviewing the medication administration record for a client who is 2 days postoperative following abdominal surgery. The nurse should recognize that which of the following medications places the client at risk for wound dehiscence?

• A. Omeprazole
• B. Zolmitriptan
• C. Prednisone
• D. Verapamil

Correct answer: C

Rationale: Corrected Rationale: Prednisone is a corticosteroid that can impair wound healing and increase the risk of wound dehiscence. Omeprazole (Choice A) is a proton pump inhibitor used to reduce stomach acid production and does not directly impact wound healing. Zolmitriptan (Choice B) is a medication used to treat migraines and does not affect wound healing. Verapamil (Choice D) is a calcium channel blocker used to treat high blood pressure and certain heart conditions, and it does not pose a significant risk for wound dehiscence.

3. In some hip surgeries, an epidural catheter for Fentanyl epidural analgesia is given. What is your nursing priority care in such a case?

• A. Instruct the client to observe strict bed rest
• B. Check for epidural catheter drainage
• C. Administer analgesia through the epidural catheter as prescribed
• D. Assess respiratory rate carefully

Correct answer: D

Rationale: The nursing priority care in a case where an epidural catheter for Fentanyl epidural analgesia is given during hip surgeries is to assess the respiratory rate carefully. Respiratory depression is a potential side effect of Fentanyl, especially when administered epidurally. Monitoring the respiratory rate is crucial to detect any signs of respiratory distress promptly. Instructing the client to observe strict bed rest (Choice A) may be necessary but is not the priority over ensuring respiratory function. Checking for epidural catheter drainage (Choice B) and administering analgesia through the epidural catheter as prescribed (Choice C) are important aspects of care, but ensuring adequate ventilation takes precedence to prevent complications.

4. Which of the following is reflected in an ECG due to hypokalemia?

• A. Tall T waves and Pathologic Q wave
• B. Widening QRS Complex and U wave
• C. None of the above
• D. Both A and B

Correct answer: B

Rationale: Hypokalemia, a condition characterized by low levels of potassium in the blood, is reflected in an ECG by a widening QRS Complex and a U wave. This is because potassium plays a key role in the electrical activity of the heart, and its deficiency can lead to abnormalities in the heart's rhythm as represented by these specific changes on the ECG. Choice A is incorrect as tall T waves and pathologic Q waves are more commonly associated with hyperkalemia or myocardial infarction, respectively, rather than hypokalemia. Choices C and D are also incorrect as they do not accurately reflect the ECG changes caused by hypokalemia.

5. Patients with congestive heart failure need to restrict their intake of:

• A. fiber
• B. sodium
• C. cholesterol
• D. saturated fat

Correct answer: B

Rationale: Patients with congestive heart failure need to restrict their intake of sodium. This restriction is crucial to prevent fluid retention, which can exacerbate the condition. While fiber is generally beneficial for heart health, sodium restriction is more critical in this scenario. Cholesterol and saturated fat intake should also be monitored, but sodium restriction takes precedence due to its direct impact on fluid balance.
