A high school nurse observes a 14-year-old female rubbing her scalp excessively in the gym. What is the most appropriate course of action for the nurse?

Correct Answer: C

Rationale: The most appropriate course of action for the nurse is to observe the hairline and scalp for possible signs of lice. The student's behavior of excessively rubbing her scalp raises concerns about a potential infestation, making it necessary to look for signs firsthand. Contacting the parents or the physician should be considered after observing for signs of lice to provide more information and take appropriate action. Requesting a private evaluation from the parents may not be required initially, as lice infestation is a common concern among children and observing for signs is the immediate step to address the situation.

Correct Answer: C

Rationale: The correct answer is Pitressin. Pitressin is a hormone replacement medication and is not classified as a neuromuscular blocker. Choices A, B, and D (Anectine, Pavulon, Mivacron) are neuromuscular blockers used during anesthesia to induce muscle relaxation for various procedures. Anectine is also known as succinylcholine, Pavulon is rocuronium, and Mivacron is mivacurium. These medications act on the neuromuscular junction to block the transmission of nerve impulses, leading to muscle relaxation.

Correct Answer: D

Rationale: The correct answer is 'Diplopia.' While drowsiness, ataxia, and salivation elevation are common side effects associated with Klonopin, diplopia is not typically linked to this medication. Diplopia, or double vision, is not a common side effect reported with the use of Klonopin. It is important to monitor patients for the known side effects such as drowsiness, ataxia, and salivation elevation when administering Klonopin. Choice A, B, and C are incorrect as they are known side effects of Klonopin, unlike diplopia which is not commonly observed with this medication.

Correct Answer: B

Rationale: The correct answer is restlessness and muscle spasms. Haldol, an antipsychotic medication, can cause extrapyramidal side effects such as muscle spasms and restlessness. These side effects can be serious and should prompt the client to seek medical attention. Shortness of breath, fatigue, dry mouth, and diarrhea are not commonly associated with Haldol use, making choices A, C, and D incorrect.

Correct Answer: A

Rationale: A chemical reaction between drugs before their administration or absorption is termed a drug incompatibility. This phenomenon commonly happens when drug solutions are mixed before intravenous administration, but it can also occur with orally administered drugs. Choices B, C, and D are incorrect because side effects, adverse events, and allergic responses occur after the administration and absorption of drugs, not prior to it.
