The client has been on vancomycin for three days. Which of the following symptoms is least concerning?

Correct Answer: B

Rationale: The correct answer is 'headache.' While vancomycin can cause ototoxicity leading to symptoms like tinnitus, vertigo, and nausea, headaches are not typically associated with vancomycin use. Therefore, headache is the least concerning symptom in this scenario. Nausea, vertigo, and tinnitus are more likely to be related to vancomycin ototoxicity and should be closely monitored and reported. Headache is a common symptom that may not be directly linked to vancomycin use.

Correct Answer: B

Rationale: Eggs are considered a complete protein because they contain all nine essential amino acids required by the human body. In contrast, corn, peanuts, and sunflower seeds are incomplete proteins as they lack one or more essential amino acids. Corn, although a staple food for many cultures, is deficient in the amino acids lysine and tryptophan. Peanuts are low in the amino acid methionine, and sunflower seeds are low in lysine. Therefore, eggs are the correct answer as a complete protein source.

Correct Answer: D

Rationale: The correct answer is the vaginal sponge. The vaginal sponge is a barrier method of contraception that, when used with foam or jelly contraception, reduces the transmission of HIV and other STDs, as well as reducing the risk of pregnancy. Intrauterine devices (IUDs), Norplant, and oral contraceptives can prevent pregnancy but not the transmission of HIV and STDs. Clients using the contraceptive methods in Choices A, B, and C should be counseled to use a chemical or barrier contraceptive to decrease the transmission of HIV or STDs.

Correct Answer: D

Rationale: A urologist consult is the most appropriate intervention for a client with visible blood at the urethral meatus and suspected genitourinary trauma. This specialist can evaluate the extent of the trauma and provide the necessary treatment. Foley catheter insertion (Choice A) and in-and-out catheter specimen for urinalysis (Choice B) are contraindicated in the presence of genitourinary trauma as they can worsen the injury. While a voided urine specimen for urinalysis (Choice C) may be ordered by the physician, it does not address the specific management needed for genitourinary trauma. Therefore, a urologist consult is the best option in this scenario.

Correct Answer: C

Rationale: Glucose is the correct value to monitor closely while a client is on total parenteral nutrition. Total parenteral nutrition solutions have high glucose concentrations, necessitating monitoring to prevent complications like hyperglycemia. Calcium, magnesium, and cholesterol are not typically closely monitored during total parenteral nutrition as they are not directly related to the solution's composition or potential associated complications.
