A nurse is preparing to administer 2.5 mL of medication intramuscularly to an adult client. Which site is safest for the nurse to use?

Correct Answer: A

Rationale: The correct answer is 'Ventrogluteal.' The ventrogluteal site is recommended for intramuscular injections in adults because it is free of major blood vessels and nerves, reducing the risk of injury or complications. Choice B, 'Dorsogluteal,' is not recommended due to the proximity of the sciatic nerve and major blood vessels. Choices C and D, 'Vastus lateralis' and 'Rectus femoris,' are sites commonly used for intramuscular injections but are more suitable for pediatric or specific population groups, not typically for adults.

Correct Answer: A

Rationale: The correct answer is A: Recent blood transfusion. A recent blood transfusion can interfere with the effectiveness of the MMR vaccine, making it a contraindication. Choice B, allergy to penicillin, is not a contraindication for the MMR vaccine. Choice C, minor acute illness, is not a contraindication unless the child has a moderate to severe illness. Choice D, low-grade fever, is not a contraindication as long as the child does not have a moderate to severe febrile illness.

Correct Answer: C

Rationale: Using perfumed toilet paper can irritate the urinary tract and increase the risk of UTI, so it should be avoided. Wearing underwear with a cotton crotch (Choice A) is a preventive measure as cotton allows for better air circulation and reduces moisture, lowering the risk of UTIs. Wiping from front to back (Choice B) helps prevent the introduction of bacteria from the anal region to the urinary tract. Urinating after intercourse (Choice D) can help flush out bacteria introduced during sexual activity, thereby reducing the risk of UTIs.

Correct Answer: C

Rationale: The correct answer is C: 'Rise slowly when sitting up.' Doxazosin can cause orthostatic hypotension, a sudden drop in blood pressure when standing up, leading to dizziness or fainting. Instructing the client to rise slowly helps prevent this adverse effect. Choices A, B, and D are incorrect. A decrease in caloric intake to reduce weight gain, an increase in dietary fiber to prevent constipation, and taking the medication each morning are not specific instructions related to managing the side effects of doxazosin.

Correct Answer: B

Rationale: Diminished deep tendon reflexes are a sign of magnesium toxicity. Magnesium sulfate can depress the central nervous system, leading to decreased reflexes. Respiratory rate of 12/min, urine output 40 mL/hr, and systolic blood pressure of 140 mm Hg are not specific findings of magnesium toxicity. Respiratory depression, oliguria, and hypotension are more concerning signs that require immediate attention.
