A healthcare provider is preparing to administer an intramuscular injection to an adult client. Which of the following injection sites should the healthcare provider select?
- A. Deltoid muscle
- B. Dorsogluteal muscle
- C. Vastus lateralis muscle
- D. Rectus femoris muscle

It is located in the upper arm and provides a sufficient area for injection. The deltoid muscle is preferred for administering vaccines and other medications that require IM administration.
A client with a new diagnosis of hypertension is receiving teaching from a healthcare provider. Which of the following statements by the client indicates an understanding of the teaching?
- A. I will decrease my intake of potassium.
- B. I will increase my intake of vitamin K.
- C. I will decrease my intake of sodium.
- D. I will increase my intake of magnesium.
Correct Answer: C
Rationale: The correct answer is C: 'I will decrease my intake of sodium.' Lowering sodium intake is essential in managing hypertension as it helps reduce blood pressure levels. Excess sodium can lead to fluid retention and increased blood volume, putting more strain on the heart and blood vessels. Therefore, this response indicates an understanding of the teaching provided.
The 5-minute Apgar of a baby delivered by C-section is recorded as 9. The most likely reason for this score is:
- A. The mottled appearance of the trunk
- B. The presence of conjunctival hemorrhages
- C. Cyanosis of the hands and feet
- D. Respiratory rate of 20-28 per minute
Correct Answer: C
Rationale: A 5-minute Apgar score of 9 typically reflects one point deduction, often for color, with cyanosis of the hands and feet (acrocyanosis) being common in newborns, especially post-C-section, due to initial circulation adjustments. Mottling or hemorrhages don't directly score points off, and a respiratory rate of 20-28 is low (normal is 30-60), potentially docking more points. Nurses recognize acrocyanosis as benign, resolving naturally, and use this score to reassure parents while monitoring transition, ensuring no further intervention is needed.
A healthcare provider is assessing a client who has fluid volume excess. Which of the following findings should the healthcare provider expect?
- A. Hypotension
- B. Bradycardia
- C. Crackles in the lungs
- D. Dry mucous membranes
Correct Answer: C
Rationale: Crackles in the lungs are indicative of fluid accumulation in the alveoli, which is a characteristic finding in clients with fluid volume excess. The crackling sound occurs due to the presence of excess fluid in the lungs, impairing normal ventilation and gas exchange. Monitoring for crackles is essential for early detection and management of fluid overload in clients.
