Correct Answer: C

Rationale: The correct answer is C: “Drink your nightly glass of milk earlier in the evening.” By suggesting the patient to drink milk earlier, it allows more time for the body to process and excrete the fluids before bedtime, reducing the likelihood of bedwetting. This intervention targets the root cause of the issue by addressing the timing of fluid intake. Explanation for why the other choices are incorrect: A: “Set your alarm clock to wake you every 2 hours, so you can get up to void.” This intervention disrupts the patient's sleep pattern and may not address the underlying cause of bedwetting. B: “Line your bedding with plastic sheets to protect your mattress.” This intervention focuses on managing the consequences of bedwetting rather than preventing it. D: “Empty your bladder completely before going to bed.” While important, this suggestion alone may not be sufficient to address the timing of fluid intake, which is crucial in reducing bedwetting frequency.

Correct Answer: B

Rationale: The correct answer is B: Cholinergics. Glaucoma is a condition characterized by increased intraocular pressure due to impaired drainage of aqueous humor. Cholinergics help to constrict the pupil and improve the outflow of aqueous humor, thus reducing intraocular pressure. This medication class is commonly used to manage glaucoma. A: Potassium-sparing diuretics are not typically used in the treatment of glaucoma. They are mainly used to manage conditions like hypertension and heart failure. C: Antibiotics are not indicated for the routine management of glaucoma. They are used to treat infections. D: Loop diuretics are not commonly used in the treatment of glaucoma. They are primarily used to manage conditions like edema and hypertension.

Correct Answer: B

Rationale: Rationale: Assessing breath sounds is crucial in evaluating respiratory status as it helps identify any signs of airway obstruction or respiratory distress. This includes listening for wheezing, crackles, or diminished breath sounds. Lung function testing (A) may not be feasible in an acute emergency situation. Oxygen saturation (C) is important but does not provide a comprehensive assessment of respiratory status. Monitoring respiratory pattern (D) and assessing respiratory rate (E) are important but do not directly assess breath sounds, which are vital in identifying immediate respiratory issues.

Correct Answer: A

Rationale: The correct answer is A: Rinsing the ears with normal saline after swimming. This is because rinsing with normal saline helps to remove excess moisture and debris, preventing bacterial growth that can lead to otitis externa. Avoiding loud noises (B) is important for overall ear health but does not specifically prevent otitis externa. Instilling antibiotic ointments regularly (C) is not recommended as it can disrupt the ear's natural flora. Avoiding cotton swabs (D) is important to prevent injury but does not directly prevent otitis externa.

Correct Answer: D

Rationale: The correct answer is D because a dyspneic patient with a tracheostomy may have difficulty speaking due to impaired airflow and mobility of the tongue. In this case, using alternative communication methods such as writing or using communication boards would be more effective. Choice A is incorrect because being blind does not directly impact communication in this scenario. Choice B is incorrect as hunger, alertness, and self-esteem do not relate to the communication challenges presented. Choice C is incorrect as depression, while important to consider, is not the primary factor impacting communication in this case.
