1. What is the expected ECG finding in a patient with hypokalemia?

A. Flattened T waves
B. Elevated ST segments
C. Widened QRS complexes
D. Widened QRS complexes on the ECG

Correct answer: A

Rationale: The correct answer is A: Flattened T waves. In hypokalemia, there is a decrease in serum potassium levels, which can lead to various ECG changes. One of the classic ECG findings associated with hypokalemia is the presence of flattened T waves. These T wave abnormalities are typically seen in multiple leads. Choice B, elevated ST segments, is not a typical ECG finding in hypokalemia. Choice C, widened QRS complexes, is more commonly associated with hyperkalemia rather than hypokalemia. Choice D is redundant and not a standard way of describing ECG findings.

2. A nurse is preparing to discharge a client who has a new diagnosis of chronic kidney disease (CKD). Which of the following referrals should the nurse plan to initiate?

A. Respiratory therapy
B. Hospice care
C. Occupational therapy
D. Dietary services

Correct answer: D

Rationale: The correct answer is D: Dietary services. Referring the client to dietary services is essential for managing nutrition, including monitoring sodium, potassium, and protein intake, which are crucial aspects of managing chronic kidney disease (CKD). Respiratory therapy (choice A) focuses on managing respiratory conditions, which are not directly related to CKD. Hospice care (choice B) is not appropriate for a new diagnosis of CKD as it is designed for end-of-life care. Occupational therapy (choice C) is beneficial for improving activities of daily living but is not the priority referral for a new CKD diagnosis.

3. What is the first intervention for a patient admitted with unstable angina?

A. Administer nitroglycerin
B. Obtain cardiac enzymes
C. Start IV fluids
D. Monitor for chest pain

Correct answer: A

Rationale: The correct first intervention for a patient admitted with unstable angina is to administer nitroglycerin. Nitroglycerin helps to relieve chest pain by dilating blood vessels and increasing blood flow to the heart, thereby reducing cardiac workload. This intervention aims to alleviate symptoms and prevent further cardiac damage. Obtaining cardiac enzymes (Choice B) is important for diagnosing a myocardial infarction but is not the initial intervention for unstable angina. Starting IV fluids (Choice C) may be indicated in specific cases like hypovolemia but is not the primary intervention for unstable angina. Monitoring for chest pain (Choice D) is essential but taking action to alleviate the pain, like administering nitroglycerin, is the primary focus in the initial management of unstable angina.

4. If a nurse misread a glucose reading as 210 mg/dL instead of 120 mg/dL and administered insulin, what should the nurse monitor for?

A. Monitor for hypoglycemia
B. Monitor for hyperglycemia
C. Administer glucose IV
D. Document the incident

Correct answer: A

Rationale: The correct answer is to monitor for hypoglycemia. In this scenario, the nurse administered insulin based on an incorrect glucose reading, which could lead to a drop in blood sugar levels. Monitoring for hypoglycemia is crucial to prevent any adverse effects on the patient's health. Choice B, monitoring for hyperglycemia, is incorrect as the administration of insulin can lead to low blood sugar levels, not high. Choice C, administering glucose IV, is not the immediate action needed as monitoring for hypoglycemia comes first. Choice D, documenting the incident, is important but not the initial priority when patient safety is at risk.

5. A nurse is planning care for a patient diagnosed with diabetes insipidus. What should be included in the care plan?

A. Monitor serum albumin levels
B. Restrict protein intake to 0.55-0.60 g/kg/day
C. Encourage the patient to increase fluid intake
D. Teach the patient to avoid alcohol

Correct answer: A

Rationale: The correct answer is to monitor serum albumin levels. In patients with diabetes insipidus, monitoring serum albumin levels is essential to assess for dehydration and nutritional deficits. Choices B, C, and D are not directly related to managing diabetes insipidus. Restricting protein intake, encouraging fluid intake, and teaching the patient to avoid alcohol are interventions that may be relevant for other medical conditions but are not specific to addressing the needs of a patient with diabetes insipidus.
