Correct Answer: D

Rationale: The correct answer is D: Labyrinthitis. This condition presents with sudden onset vertigo, nausea, vomiting, tinnitus, and hearing loss, which are all symptoms described by the patient. Labyrinthitis is commonly caused by a viral infection affecting the inner ear, leading to inflammation of the labyrinth. This inflammation disrupts the balance and hearing functions of the inner ear, resulting in the symptoms mentioned. A: Ossiculitis involves inflammation of the middle ear bones, typically causing conductive hearing loss, not the sudden onset of vertigo and other symptoms described. B: Mnire's disease is characterized by recurrent episodes of vertigo, tinnitus, and hearing loss, but it typically does not present with sudden onset incapacitating vertigo. C: Ototoxicity is caused by exposure to certain medications or chemicals that damage the inner ear structures, leading to hearing loss. While hearing loss is a symptom, the sudden onset of vertigo is not typically associated with ototoxicity.

Correct Answer: D

Rationale: The correct answer is D: Hold the condom by the cuff upon withdrawal. This is important because holding the condom by the cuff helps prevent any potential spillage of bodily fluids. During withdrawal, holding the condom by the base prevents it from slipping off and minimizes the risk of exposure to sexually transmitted infections. Explanation of why other choices are incorrect: A: Attaching the condom prior to erection is incorrect as it may lead to breakage or slipping off during intercourse. B: Reusing a condom with the same partner is highly discouraged due to the risk of breakage, reduced effectiveness, and potential exposure to infections. C: Using skin lotion as a lubricant is not recommended as it can degrade the condom material, increasing the risk of breakage.

Correct Answer: B

Rationale: The correct answer is B: Count and inspect each perineal pad that the patient uses. This method directly measures postoperative blood loss and allows for accurate monitoring. It provides quantitative data to assess the severity of hemorrhage. A: Having the patient void and have bowel movements using a commode rather than toilet does not directly measure blood loss and may not provide accurate monitoring. C: Swabbing the patient's perineum for the presence of blood is not as accurate as directly counting and inspecting perineal pads. D: Leaving the patient's perineum open to air does not provide a method for quantifying blood loss and may not be as reliable as inspecting perineal pads.

Correct Answer: B

Rationale: The correct answer is B: Retinopathy. Tadalafil (Cialis) is contraindicated in patients with retinopathy due to the potential risk of worsening vision problems. Retinopathy is a serious eye condition commonly associated with diabetes, and using tadalafil can lead to further complications in the eyes. It is crucial for patients with retinopathy to avoid medications that can exacerbate their eye condition. Incorrect choices: A: Cataracts - Cataracts do not contraindicate the use of tadalafil. Tadalafil does not have a direct negative impact on cataracts. C: Hypotension - Hypotension is not a contraindication for tadalafil use. In fact, tadalafil can cause a drop in blood pressure, so it should be used with caution in patients with hypotension. D: Diabetic nephropathy - Diabetic nephropathy is not a direct contraindication for tadalafil use. Tadalafil is generally

Correct Answer: C

Rationale: Step 1: After mastoid surgery, patients may experience pain and dizziness, hence addressing the safe use of analgesics and antivertiginous agents is crucial for symptom management. Step 2: Analgesics help in managing post-operative pain, while antivertiginous agents help control dizziness, reducing the risk of falls. Step 3: Educating the patient on safe use ensures proper pain and symptom management, preventing complications. Step 4: Other choices are incorrect as they do not directly address immediate post-operative care needs such as pain and dizziness management.
