Correct Answer: A

Rationale: The correct answer is A: Blowing up balloons. Blowing up balloons involves the activation of the facial muscles, which helps prevent muscle atrophy in patients with Bell's palsy. This exercise promotes muscle strength and prevents weakness. Deliberately frowning (B), smiling repeatedly (C), and whistling (D) do not specifically target the facial muscles involved in Bell's palsy and may not be as effective in preventing muscle atrophy.

Correct Answer: D

Rationale: The correct answer is D because documenting the patient's pain intensity using a pain scale (8 out of 10) is crucial for assessing the severity of the chest pain. This information helps in determining the appropriate intervention and monitoring the effectiveness of treatment. Choice A is irrelevant as it does not provide any useful information about the patient's condition. Choice B is important for neurological assessment but not specifically related to chest pain. Choice C is not as critical as knowing the current pain level.

Correct Answer: C

Rationale: The correct choice is C because if no urine is obtained, it indicates that the catheter is not in the urethra. The nurse should remove the catheter, wipe with alcohol to maintain cleanliness, and reinsert after lubrication to ensure proper placement in the urethra. This step-by-step approach allows for a more accurate catheter insertion and prevents potential complications. Choice A is incorrect as discarding the catheter and starting over without addressing the issue does not solve the problem. Choice B is incorrect as filling the balloon with sterile water is not relevant to the situation of catheter misplacement. Choice D is incorrect as leaving the catheter in the vagina can lead to infection and is not a recommended practice.

Correct Answer: C

Rationale: The correct answer is C: A barrier to hospice care for this patient. The lack of knowledge about hospice care can be perceived as a barrier to accessing this type of care for the patient and her family. Understanding hospice care is crucial in making informed decisions about end-of-life care options. This lack of knowledge does not necessarily indicate lack of education (choice A), language barrier (choice B), or inability to grasp American concepts of health care (choice D), as hospice care is a universal concept that transcends cultural and educational backgrounds.

Correct Answer: A

Rationale: The correct answer is A because instilling the medication in the conjunctival sac allows for direct absorption into the eye tissues. This method ensures that the medication reaches the target area for treating glaucoma effectively. Maintaining a supine position (choice B) or keeping the eyes closed (choice C) after administration does not enhance absorption and may lead to wasted medication. Applying the medication to the sclera (choice D) is incorrect as it does not target the specific area needed for treating glaucoma.
