1. What ECG changes should be monitored in a patient with hypokalemia?

A. Flattened T waves and prominent U waves
B. Elevated ST segments and wide QRS complexes
C. Tall T waves and flattened QRS complexes
D. Widened QRS complexes and decreased P wave amplitude

Correct answer: A

Rationale: The correct answer is A: Flattened T waves and prominent U waves. In hypokalemia, there is a decrease in potassium levels, which can lead to ECG changes such as flattened T waves and prominent U waves. These changes are classic findings associated with hypokalemia. Choices B (Elevated ST segments and wide QRS complexes), C (Tall T waves and flattened QRS complexes), and D (Widened QRS complexes and decreased P wave amplitude) are all incorrect. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia. Tall T waves and flattened QRS complexes, as well as widened QRS complexes and decreased P wave amplitude, do not represent the typical ECG changes seen in hypokalemia.

2. What is the first action a healthcare provider should take for a patient with possible acute coronary syndrome?

A. Administer sublingual nitroglycerin
B. Get IV access
C. Auscultate heart sounds
D. Obtain cardiac enzymes

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the initial priority action for a patient with possible acute coronary syndrome. Nitroglycerin helps dilate blood vessels, reduce chest pain, and improve blood flow to the heart muscle. This helps in relieving symptoms and preventing further damage to the heart. Establishing IV access, auscultating heart sounds, and obtaining cardiac enzymes are important steps in the assessment and management of acute coronary syndrome but are not the first actions to be taken. IV access may be needed for administering medications or fluids, auscultating heart sounds helps in assessing the heart's function, and obtaining cardiac enzymes aids in diagnosing a heart attack.

3. When planning care for a patient with diabetes insipidus, what should the nurse include in the plan?

A. Monitor serum albumin levels
B. Avoid alcohol
C. Teach the patient to increase fluids
D. Increase exercise to reduce stress

Correct answer: B

Rationale: The correct answer is B: 'Avoid alcohol.' Alcohol consumption can exacerbate dehydration in patients with diabetes insipidus, so it is essential to advise them to avoid alcohol. Monitoring serum albumin levels (choice A) is not directly related to managing diabetes insipidus. Teaching the patient to increase fluids (choice C) is not recommended as it can worsen the condition by further diluting the urine. Increasing exercise to reduce stress (choice D) is not a primary intervention for managing diabetes insipidus.

4. What teaching should be provided to a patient after cataract surgery?

A. Avoid NSAIDs
B. Avoid bright lights
C. Wear dark glasses while outdoors
D. Use warm compresses

Correct answer: A

Rationale: The correct teaching to provide to a patient after cataract surgery is to avoid NSAIDs. NSAIDs should be avoided to reduce the risk of bleeding post-surgery. Choices B, C, and D are not directly related to post-cataract surgery care. Avoiding bright lights and wearing dark glasses while outdoors may be beneficial for eye comfort but are not specific postoperative instructions. Using warm compresses is also not a standard teaching after cataract surgery.

5. A patient with GERD is receiving dietary teaching from a nurse. What should the nurse recommend?

A. Avoid mint and pepper
B. Increase fluid intake before meals
C. Eat three large meals per day
D. Avoid drinking water with meals

Correct answer: A

Rationale: The correct recommendation for a patient with GERD is to avoid foods like mint and pepper, as these can help reduce gastric acid secretion and alleviate symptoms. Mint and pepper are known to relax the lower esophageal sphincter, leading to increased reflux. Increasing fluid intake before meals (choice B) may worsen GERD symptoms by distending the stomach. Eating three large meals per day (choice C) can also aggravate GERD because large meals can lead to increased gastric pressure and reflux. Avoiding drinking water with meals (choice D) is generally recommended for GERD; however, the most crucial advice in this case is to avoid mint and pepper for better symptom management.
