1. What ECG changes are expected in a patient with hypokalemia?

A. Flattened T waves
B. Prominent U waves
C. Widened QRS complexes
D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are an early indicator of hypokalemia on an ECG. Hypokalemia primarily presents with flattened T waves, not prominent U waves, widened QRS complexes, or tall T waves. Prominent U waves are associated with hypokalemia only in severe cases. Widened QRS complexes are more indicative of hyperkalemia, while tall T waves are seen in hyperkalemia as well.

2. What dietary recommendations should be given to a patient with GERD?

A. Avoid mint and spicy foods
B. Eat large meals before bed
C. Increase fluid intake during meals
D. Drink milk as a snack

Correct answer: A

Rationale: The correct dietary recommendation for a patient with GERD is to avoid mint and spicy foods. These foods can trigger symptoms of GERD and lead to acid reflux. Choice B is incorrect because eating large meals before bed can exacerbate GERD symptoms by increasing the likelihood of acid reflux during sleep. Choice C is incorrect as increasing fluid intake during meals can worsen GERD symptoms by distending the stomach, leading to increased pressure on the lower esophageal sphincter. Choice D is also incorrect because while milk may provide temporary relief for some individuals, it is not a recommended long-term solution for managing GERD.

3. What should be monitored in a patient with diabetes insipidus?

A. Monitor urine specific gravity for values below 1.005
B. Monitor for increased thirst
C. Monitor serum albumin levels
D. Monitor blood pressure closely

Correct answer: A

Rationale: In a patient with diabetes insipidus, monitoring urine specific gravity for values below 1.005 is crucial. Low urine specific gravity indicates excessive water loss, a key characteristic of diabetes insipidus. Monitoring for increased thirst (choice B) may be a symptom presented by the patient, but it does not directly reflect the condition's severity. Monitoring serum albumin levels (choice C) is not typically associated with diabetes insipidus. Monitoring blood pressure closely (choice D) is not a primary concern in diabetes insipidus unless severe dehydration leads to hypotension.

4. A nurse is planning care for a client who has acute post-streptococcal glomerulonephritis. Which of the following interventions should the nurse include in the client's plan?

A. Encourage a high-protein diet
B. Increase the client's fluid intake
C. Administer diuretics
D. Weigh the client twice a week

Correct answer: C

Rationale: Administering diuretics is a crucial intervention for a client with acute post-streptococcal glomerulonephritis as it helps reduce edema by increasing urine output and managing symptoms of glomerulonephritis. Encouraging a high-protein diet (Choice A) is not recommended in this case because it can put additional stress on the kidneys. Increasing fluid intake (Choice B) may worsen edema in these clients. Weighing the client twice a week (Choice D) is important for monitoring fluid balance but is not as immediate and directly beneficial as administering diuretics.

5. What teaching should be provided to a patient following surgical removal of a cataract?

A. Avoid NSAIDs
B. Wear dark glasses while outdoors
C. Creamy white drainage is normal
D. Reduce phosphorus intake to 700 mg/day

Correct answer: A

Rationale: The correct teaching to provide to a patient following surgical removal of a cataract is to avoid NSAIDs. NSAIDs can increase the risk of bleeding at the surgical site, so it is important to steer clear of them. Choice B, wearing dark glasses while outdoors, may be recommended post-surgery to protect the eyes from bright light, but it is not the priority teaching in this case. Choice C, stating that creamy white drainage is normal, is not accurate as drainage from the eye should be monitored and reported. Choice D, reducing phosphorus intake to 700 mg/day, is unrelated to post-cataract surgery care and is not a necessary teaching point.
