When taking a patient’s history, she mentions being depressed and dealing with an anxiety disorder. Which of the following medications would the patient most likely be taking?

Correct Answer: A

Rationale: The correct answer is Amitriptyline (Elavil) as it is a tricyclic antidepressant commonly used to treat symptoms of depression and anxiety disorders. Amitriptyline works by increasing the levels of certain neurotransmitters in the brain to improve mood. Choices B, C, and D are incorrect. Calcitonin is a hormone used in the treatment of osteoporosis; Pergolide mesylate is a dopamine agonist used in Parkinson's disease; Verapamil is a calcium channel blocker used to treat high blood pressure and certain heart conditions, not mental health disorders.

Correct Answer: D

Rationale: A platelet count of 25,000/microliter indicates severe thrombocytopenia, which increases the risk of bleeding. It is crucial to initiate bleeding precautions, including regularly checking for signs of bleeding such as examining urine and stool for blood. Monitoring for fever every 4 hours (Choice A) should be included for neutropenic precautions, not specifically related to platelet count. Requiring visitors to wear respiratory masks and protective clothing (Choice B) is more relevant for patients with airborne precautions. Considering transfusion of packed red blood cells (Choice C) is not indicated for low platelet count but is more appropriate for managing anemia or low hemoglobin levels.

Correct Answer: B

Rationale: Increased intracranial pressure after head trauma can lead to serious complications. Repeated vomiting is a concerning sign as it can indicate stimulation of the vomiting center within the brainstem due to increased pressure. This can be an early indicator of raised intracranial pressure and the need for urgent medical intervention. Bulging anterior fontanel may not be immediately apparent in a 4-year-old child and is more common in infants. Signs of sleepiness at a particular time of day are not specific to increased intracranial pressure. Inability to read short words from a distance of 18 inches may indicate vision problems but is not directly related to intracranial pressure.

Correct Answer: C

Rationale: Petechiae on the soft palate are not a typical finding in scarlet fever. Scarlet fever is caused by group A Streptococcus bacteria, often presenting with a strawberry tongue, red and swollen pharynx, and a sandpaper-like rash. The presence of petechiae on the soft palate is more commonly associated with conditions like rubella rather than scarlet fever. Therefore, this description is not correct in the context of scarlet fever.

Correct Answer: B

Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day. Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.
