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 patient has been diagnosed with a thrombotic stroke. What are the expected manifestations?

A. Gradual loss of function on one side of the body
B. Sudden loss of consciousness
C. Seizures and confusion
D. Loss of sensation in the affected limb

Correct answer: A

Rationale: The correct answer is A: 'Gradual loss of function on one side of the body.' Thrombotic strokes lead to slow and progressive symptoms as a result of decreased blood flow to a specific area of the brain. Choices B, C, and D are incorrect because sudden loss of consciousness, seizures, confusion, and loss of sensation in the affected limb are not typical manifestations of a thrombotic stroke.

3. A patient with pre-dialysis end-stage kidney disease is asking for dietary recommendations. What should the nurse suggest?

A. Limit protein intake
B. Limit potassium intake
C. Restrict sodium intake
D. Limit phosphorus intake to 700mg/day

Correct answer: D

Rationale: In patients with pre-dialysis end-stage kidney disease, it is crucial to limit phosphorus intake to 700mg/day to manage their condition. High phosphorus levels can lead to complications such as bone and heart problems. Limiting protein intake is essential in later stages of kidney disease, particularly in dialysis patients to reduce the buildup of waste products. While limiting potassium and restricting sodium intake are also important in kidney disease management, the priority for a patient with pre-dialysis end-stage kidney disease is to control phosphorus levels.

4. What dietary recommendation should be given to a patient with GERD?

A. Avoid mint and spicy foods
B. Eat large meals before bedtime
C. Consume liquids with meals
D. Eat three large meals per day

Correct answer: A

Rationale: The correct recommendation for a patient with GERD is to avoid mint and spicy foods. Mint and spicy foods can aggravate GERD symptoms by relaxing the lower esophageal sphincter and increasing stomach acid production, leading to acid reflux. Choices B, C, and D are incorrect. Eating large meals before bedtime can worsen GERD symptoms as lying down can promote acid reflux. Consuming liquids with meals can also exacerbate GERD by increasing stomach distension and pressure on the lower esophageal sphincter. Eating three large meals per day can overload the stomach and trigger acid reflux episodes in patients with GERD.

5. What are the early signs of compartment syndrome?

A. Unrelieved pain, pallor, and pulselessness
B. Localized redness and swelling
C. Fever and infection
D. Loss of sensation in the affected area

Correct answer: A

Rationale: The correct answer is A: Unrelieved pain, pallor, and pulselessness. These signs are typical early indicators of compartment syndrome, suggesting compromised circulation. Choice B, localized redness and swelling, can be seen in conditions like cellulitis but are not specific to compartment syndrome. Choice C, fever and infection, are not characteristic early signs of compartment syndrome. Choice D, loss of sensation in the affected area, is more indicative of nerve damage rather than being one of the early signs of compartment syndrome.
