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: Correct Answer: D Rationale: 1. Clear, watery fluid draining from the ear post-accident indicates a possible cerebrospinal fluid (CSF) leak, a serious condition requiring immediate medical attention to prevent complications such as meningitis. 2. CSF leak can result from a basilar skull fracture, common in head injuries like motorcycle accidents. 3. Prompt reporting of this finding by the nurse is crucial for timely intervention and prevention of potential life-threatening complications. Summary: A: Visualizing the malleus during otoscopic examination is normal and not an immediate concern in this scenario. B: A pearly gray tympanic membrane is a normal finding and does not indicate a serious issue post-accident. C: Tenderness in the mastoid area may suggest injury but is not as urgent as clear, watery fluid drainage indicative of a CSF leak.

Correct Answer: C

Rationale: The correct answer is C: "This must be very difficult for you." This response acknowledges the patient's emotional state and shows empathy without making assumptions or dismissing their feelings. It validates the patient's emotions and opens up the opportunity for further discussion or support. Rationale: 1. A: "I know how you are feeling" assumes the tutor knows the exact emotions of the patient, which can come off as insincere or dismissive. 2. B: "You have lived a long life" does not address the patient's emotional distress or provide comfort in the face of a terminal illness. 3. D: "Life can be so unfair" does not directly address the patient's feelings and may come off as generic or cliché.

Correct Answer: B

Rationale: Step 1: Immunotherapy injections can cause allergic reactions. Step 2: Monitoring post-injection is crucial to detect and manage any potential adverse reactions promptly. Step 3: Staying in the clinic for 30 minutes allows for immediate intervention if needed. Step 4: This ensures patient safety and reduces the risk of severe reactions. Summary: A: Epinephrine is not typically given before immunotherapy injections. C: Therapeutic response may take longer than 3 months to show. D: Immunotherapy is usually given via subcutaneous route, not intravenous.

Correct Answer: B

Rationale: The correct answer is B because hearing loss and tinnitus caused by aspirin are typically irreversible. Aspirin is known to cause ototoxicity, which can lead to permanent damage to the auditory system. The nurse should inform the patient that the hearing loss and tinnitus may not improve even after discontinuing aspirin. Choice A is incorrect because hearing loss caused by aspirin is usually permanent. Choice C is incorrect because aspirin is a known cause of tinnitus and hearing loss. Choice D is incorrect because tolerance to aspirin does not prevent or reverse ototoxic effects like tinnitus and hearing loss.

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.

Correct Answer: B

Rationale: The correct answer is B: Total placenta previa. In this condition, the placenta completely covers the cervix, posing a risk of severe bleeding during vaginal delivery. Cesarean birth is necessary to avoid potential life-threatening complications for both the mother and the baby. Partial abruptio placentae (choice A) involves premature separation of the placenta, but it doesn't always require a cesarean birth. Ectopic pregnancy (choice C) occurs when the fertilized egg implants outside the uterus, typically requiring surgical intervention but not always a cesarean birth. Eclampsia (choice D) is a serious condition characterized by high blood pressure and seizures, but it doesn't always necessitate cesarean birth unless there are other complications that require it.

Correct Answer: B

Rationale: The correct answer is B because verifying tube placement before feeding is essential to prevent pulmonary aspiration. If the tube is not correctly positioned in the stomach, there is a risk of feeding going into the lungs. Observing the color of gastric contents (A) may not always indicate correct placement. Adding blue food coloring (C) is unnecessary and could cause confusion. Running the formula over 12 hours (D) does not address the risk of pulmonary aspiration and does not ensure proper tube placement.

Correct Answer: B

Rationale: The correct answer is B: In the morning. This is because scheduling physical therapy in the morning allows the patient to benefit from increased energy levels and improved muscle strength and function after a night of rest. Morning sessions can also help set a positive tone for the rest of the day. Choice A: Immediately after meals can lead to discomfort and potential complications like indigestion or reflux. Choice C: Before bedtime may be too late in the day when fatigue levels are higher and may disrupt sleep patterns. Choice D: In the early evening may be less effective as fatigue accumulates throughout the day, and the patient may not have the same level of energy and focus as in the morning.
