When caring for a patient with a colostomy, which nursing action is most important?

A. Monitor the colostomy for signs of infection.

B. Empty the colostomy bag when it is half full.

C. Encourage the patient to eat smaller, more frequent meals.

D. Apply a skin barrier to prevent irritation.

Correct Answer: B
Rationale: Emptying the colostomy bag when it is half full is the most important nursing action when caring for a patient with a colostomy. This practice helps prevent leakage, reduces the risk of skin irritation, and promotes patient comfort. Monitoring for signs of infection (Choice A) is essential but not as crucial as maintaining proper colostomy care. Encouraging the patient to eat smaller, more frequent meals (Choice C) can be beneficial for colostomy patients but is not as critical as ensuring timely emptying of the colostomy bag. Applying a skin barrier to prevent irritation (Choice D) is important, but ensuring timely emptying of the colostomy bag takes precedence in preventing complications associated with a colostomy.

A client with hypertension is prescribed atenolol. Which of the following findings should the nurse include as adverse effects of this medication?

• A. Cough
• B. Tremor
• C. Constipation
• D. Bradycardia

Correct Answer: D
Rationale: Correct. Bradycardia is a known adverse effect of atenolol, a beta-blocker medication commonly used to treat hypertension. Atenolol can slow down the heart rate, leading to bradycardia. The nurse should monitor the client for signs of bradycardia, such as dizziness, fatigue, or fainting. Choices A, B, and C are incorrect because cough, tremor, and constipation are not typically associated with atenolol use.

Which action by the nurse will help reduce the risk of venous thromboembolism (VTE) in a postoperative patient?

• A. Encourage early ambulation and leg exercises.
• B. Apply compression stockings to the patient's legs.
• C. Administer anticoagulants as prescribed.
• D. Elevate the patient's legs to promote circulation.

Correct Answer: A
Rationale: The correct answer is to encourage early ambulation and leg exercises. By promoting early ambulation and leg exercises, blood flow is enhanced, reducing the risk of venous thromboembolism (VTE) in postoperative patients. Choice B, applying compression stockings, helps prevent VTE but is not as effective as early ambulation and exercises. Choice C, administering anticoagulants, is important in VTE prevention but does not directly address improving circulation through physical activity. Choice D, elevating the patient's legs, may be beneficial for circulation in specific cases but is not as effective in preventing VTE as early ambulation and leg exercises.

A nurse is preparing to perform a 12-lead electrocardiogram (ECG). Which of the following instructions should the nurse provide to the client?

• A. Remain still once the gel pads are attached
• B. I will be placing electrodes on your chest
• C. I will lower the head of your bed so you can sit up
• D. Breathe normally throughout the procedure

Correct Answer: A
Rationale: The correct answer is A. Instructing the client to remain still once the gel pads are attached is crucial to obtaining accurate ECG readings. Choice B is incorrect as electrodes are typically placed on the chest, not the breast. Choice C is incorrect because the client should lie flat during an ECG, not sit up. Choice D is incorrect because the client should breathe normally, rather than holding their breath, throughout the procedure.

What is the primary goal when caring for a patient with chronic obstructive pulmonary disease (COPD)?

• A. Maintain the patient's oxygen saturation above 90%.
• B. Administer bronchodilators as prescribed.
• C. Improve the patient's nutritional intake.
• D. Encourage the patient to limit physical activity.

Correct Answer: A
Rationale: The correct answer is to maintain the patient's oxygen saturation above 90% when caring for a patient with COPD. In COPD, impaired gas exchange leads to decreased oxygen levels in the blood. By ensuring oxygen saturation remains above 90%, healthcare providers can prevent hypoxia and its complications. Administering bronchodilators as prescribed (Choice B) is an important intervention in managing COPD symptoms, but it is not the primary goal. Improving the patient's nutritional intake (Choice C) and encouraging the patient to limit physical activity (Choice D) are also essential aspects of COPD management, but they are not the primary goal when caring for a patient with this condition.
