1. Which vitamin deficiency is most associated with night blindness?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin D

Correct answer: A

Rationale: The correct answer is Vitamin A. Vitamin A deficiency leads to night blindness because this vitamin is crucial for the formation of rhodopsin, a photopigment in the retina. Rhodopsin is essential for vision in low-light conditions. Vitamin B12 deficiency can lead to anemia and neurological issues but is not directly related to night blindness. Vitamin C deficiency can cause scurvy, affecting connective tissues, but not night vision. Vitamin D deficiency can lead to bone disorders but is not primarily associated with night blindness.

2. Which laboratory value is most important to monitor for a patient receiving heparin therapy?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Partial thromboplastin time (PTT)
• D. International normalized ratio (INR)

Correct answer: C

Rationale: The correct answer is C, Partial thromboplastin time (PTT). PTT is monitored to assess the therapeutic effect of heparin therapy. It helps ensure that the heparin levels are within the desired range to prevent either clotting or excessive bleeding. Platelet count (A) is important but does not directly assess heparin's therapeutic effect. Prothrombin time (PT) (B) and International normalized ratio (INR) (D) are used to monitor patients on warfarin, not heparin therapy.

3. What is the priority intervention for a patient experiencing an acute asthma attack?

• A. Administering a bronchodilator
• B. Encouraging the patient to drink fluids
• C. Applying a high-flow oxygen mask
• D. Performing chest physiotherapy

Correct answer: A

Rationale: Administering a bronchodilator is the priority intervention in an acute asthma attack. Bronchodilators help to quickly open the airways, relieve bronchospasm, and improve breathing. Encouraging the patient to drink fluids may be beneficial for other conditions but is not the priority in an acute asthma attack. Applying a high-flow oxygen mask may be necessary in severe cases of respiratory distress but is not the initial priority when managing an acute asthma attack. Performing chest physiotherapy is not indicated as the primary intervention for an acute asthma attack and may not address the immediate need to open the airways and improve breathing.

4. Which assessment finding would most likely indicate a complication of enteral tube feeding?

• A. Abdominal distension
• B. Weight gain
• C. Decreased bowel sounds
• D. Diarrhea

Correct answer: A

Rationale: Abdominal distension in a patient receiving enteral tube feeding may indicate a complication such as intolerance to feeding, delayed gastric emptying, or obstruction. Abdominal distension is a common sign of gastrointestinal issues related to enteral tube feeding. Weight gain is typically an expected outcome if the patient is receiving adequate nutrition. Decreased bowel sounds may indicate decreased motility but are not specific to enteral tube feeding complications. Diarrhea can occur due to various reasons, including infections, medications, or dietary changes, but it is not the most likely indication of a complication in enteral tube feeding.

5. A client is recovering from abdominal surgery and has a nasogastric (NG) tube in place. The nurse notes that the client is experiencing nausea despite the NG tube being patent. What is the nurse's best action?

• A. Increase the suction on the NG tube.
• B. Administer an antiemetic as prescribed.
• C. Irrigate the NG tube with saline.
• D. Reposition the client to the left side.

Correct answer: B

Rationale: Administering an antiemetic as prescribed is the best action for the nurse to take when a client with a patent NG tube is experiencing nausea. This intervention can help relieve nausea effectively. Increasing suction on the NG tube (Choice A) may not address the underlying cause of the nausea and could potentially lead to complications. Irrigating the NG tube with saline (Choice C) is not indicated for addressing nausea in this scenario. Repositioning the client to the left side (Choice D) is not the priority intervention for nausea in a client with a patent NG tube.
