A 56-year-old patient has come to the clinic for his routine eye examination and is told he needs bifocals. The patient asks the nurse what change in his eyes has caused his need for bifocals. How should the nurse respond?

Correct Answer: C

Rationale: The correct answer is C because it accurately explains the physiological change in the eye that leads to the need for bifocals. As individuals age, there is a gradual thickening of the lens of the eye, which affects the eye's ability to accommodate for near vision. This thickening makes it harder for the eye to focus on close objects, necessitating the use of bifocals to correct this near vision issue. Choices A, B, and D are incorrect because they do not provide a scientifically accurate explanation for the need for bifocals in older individuals. Option A is dismissive and does not address the specific change in the eye that leads to the need for bifocals. Option B implies aging as a general concept without specifying the relevant change in the eye. Option D incorrectly states that the eye gets shorter as we age, which is not the reason for needing bifocals.

Correct Answer: D

Rationale: The correct answer is D. The nurse should arrange for a referral to a rehabilitation facility for vision training. This option directly addresses the patient's inability to read medication bottles accurately due to a vision problem. Vision training can help improve the patient's ability to manage medication independently. A: Asking the social worker to investigate alternative housing arrangements is not relevant to the patient's vision problem affecting medication management. B: Asking the social worker to investigate community support agencies may not directly address the patient's vision issue and medication management. C: Encouraging the patient to explore surgical corrections for the vision problem is not appropriate without considering less invasive options first, such as vision training.

Correct Answer: D

Rationale: Rationale: 1. Indispensable amino acids, also known as essential amino acids, must be obtained through the diet as the body cannot synthesize them. 2. Amino acids are the building blocks of proteins, so mentioning "indispensable amino acids" indicates understanding of essential dietary proteins. 3. Triglycerides are fats, not proteins, and not related to essential amino acids. 4. Dispensable amino acids can be synthesized by the body, so mentioning them would not indicate understanding of essential proteins.

Correct Answer: C

Rationale: The nurse will use the history of angina for "B" when using SBAR because it provides relevant background information about the patient's cardiac condition. This helps the nurse understand the context of the current situation and make appropriate decisions. Pulse rate of 108 (choice B) is a specific vital sign and not an appropriate choice for "B" in SBAR. Having chest pain (choice A) is important but does not provide the necessary background information like the history of angina does. Oxygen being needed (choice D) is a current intervention and not relevant for "B" in SBAR, which focuses on providing background information.

Correct Answer: C

Rationale: The correct answer is C. When a patient's level of consciousness declines and becomes unresponsive, it may indicate a potential overdose of analgesics. To ensure patient safety, IV analgesics should be withheld and replaced with transdermal analgesics, which provide a more controlled and gradual release of medication. This switch helps prevent further overdose and adverse effects. Continuing the current pain control regimen (Choice A) may worsen the situation. Placing the pain control regimen on hold (Choice B) may lead to inadequate pain management. Reducing analgesic dosages (Choice D) may not be sufficient in addressing the overdose issue.

Correct Answer: C

Rationale: The correct answer is C: Risk for infection related to altered immunologic response. This is the priority nursing diagnosis for a patient preparing for hematopoietic stem cell transplant (HSCT) because the patient's immune system will be severely compromised post-transplant, leading to a high risk of infections. It is crucial to prioritize infection prevention to ensure the patient's safety and well-being. Choice A is incorrect because while fatigue is common in cancer patients, it is not the priority in this case where infection risk is higher. Choice B is incorrect as altered nutrition can be addressed after managing the risk for infection. Choice D is incorrect as body image disturbance is important but not as critical as preventing infections in this highly vulnerable patient population.

Correct Answer: A

Rationale: The correct answer is A: Assessing for mouth droop and decreased lateral eye gaze. After a radical mastoidectomy, the nurse should prioritize assessing for signs of facial nerve damage, such as mouth droop and decreased lateral eye gaze, which can indicate injury to the facial nerve during surgery. This is crucial as immediate intervention may be needed to prevent long-term complications. Choices B, C, and D are incorrect: B: Assessing for increased middle ear pressure and perforated ear drum is not the priority postoperative care for a radical mastoidectomy patient. C: Assessing for gradual onset of conductive hearing loss and nystagmus is not the priority as these are not immediate concerns postoperatively. D: Assessing for scar tissue and cerumen obstructing the auditory canal is not the priority as these are not immediate postoperative complications that require urgent attention.

Correct Answer: C

Rationale: The correct answer is C: Viral set point. The viral set point refers to the stable level of HIV in the body after the initial infection. This state indicates a balance between viral replication and the immune response. The other choices are incorrect because: A) Static stage implies no change, which is not the case with HIV levels fluctuating; B) Latent stage refers to a period of inactivity, not the stable state described; D) Window period is the time between infection and detectable antibodies, not the equilibrium state described.

Correct Answer: B

Rationale: The correct answer is B: Keep the lesions clean and dry. This intervention helps prevent infection and promotes healing. Cleaning the lesions reduces the risk of secondary infections and discomfort. Keeping the area dry can also help alleviate pain and discomfort associated with moisture. Covering with a topical antibiotic (A) may not address pain directly and could potentially irritate the lesions. Applying a topical NSAID (C) may provide some pain relief but does not address the primary need to keep the lesions clean and dry. Remaining on bed rest (D) is not necessary for managing acute pain related to genital lesions.
