1. What are the expected changes on an ECG for a patient with hypokalemia?

A. Flattened T waves
B. Prominent U waves
C. ST elevation
D. Wide QRS complexes

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.

2. A patient reports abdominal cramping during an enema administration. What action should the nurse take?

A. Increase the flow of the enema
B. Lower the height of the enema solution container
C. Stop the enema procedure
D. Remove the enema tubing

Correct answer: B

Rationale: When a patient experiences abdominal cramping during an enema administration, the nurse should lower the height of the enema solution container. Lowering the container helps to relieve cramping by slowing the flow of the solution, making it more comfortable for the patient. Increasing the flow (Choice A) would exacerbate the cramping. Stopping the procedure (Choice C) may not be necessary if adjusting the height resolves the issue. Removing the enema tubing (Choice D) is not the initial action indicated for cramping; adjusting the height is the more appropriate intervention.

3. 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.

4. What is the priority intervention for a patient with unstable angina?

A. Administer nitroglycerin
B. Establish IV access
C. Auscultate heart sounds
D. Administer aspirin

Correct answer: A

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with unstable angina as it helps dilate blood vessels, improve blood flow to the heart, relieve chest pain, and prevent further cardiac damage. Establishing IV access (choice B) may be important but is not the priority over administering nitroglycerin in this scenario. Auscultating heart sounds (choice C) and administering aspirin (choice D) are also important aspects of managing unstable angina, but they are not the immediate priority intervention when a patient is experiencing chest pain.

5. A nurse is assessing a client who has a permanent spinal cord injury and is scheduled for discharge. Which of the following client statements indicates that the client is coping effectively?

A. I would like to play wheelchair basketball. When I get stronger, I think I'll look for a league.
B. I'm glad I'll only be in this wheelchair temporarily. I can't wait to get back to running.
C. I'm so upset that this happened to me. What did I do to deserve this?
D. I feel like I'll never be able to do anything that I want to again. All I am is a burden to my family.

Correct answer: A

Rationale: Choice A is the correct answer because it shows that the client has accepted their disability and is looking towards the future with realistic goals. This positive attitude and focus on engaging in activities that are achievable despite the disability indicate effective coping mechanisms. Choice B is incorrect as it reflects denial of the permanent nature of the disability. Choice C is incorrect as it shows feelings of anger and possible self-blame, which are not indicative of effective coping. Choice D is incorrect as it demonstrates a sense of hopelessness and self-perceived burden, which are signs of maladaptive coping.
