The healthcare provider is preparing to administer an IM injection to an adult client. Which site is the preferred location for this injection?

A. Deltoid muscle

B. Vastus lateralis muscle

C. Ventrogluteal muscle

D. Dorsogluteal muscle

Correct Answer: C
Rationale: The ventrogluteal site is the preferred site for IM injections in adults due to its muscle mass and low risk of nerve injury. The deltoid muscle, although commonly used for vaccines in adults due to easy accessibility, has a smaller muscle mass making it less ideal for IM injections. The vastus lateralis muscle is typically used in infants and young children, not in adults. The dorsogluteal site has a higher risk of injury to the sciatic nerve and is no longer recommended for IM injections in any age group.

A client with cirrhosis is experiencing pruritus. Which intervention should the nurse include in the care plan?

• A. Administer antihistamines as prescribed
• B. Apply alcohol-based lotions to the skin
• C. Encourage frequent baths with hot water
• D. Limit fluid intake

Correct Answer: A
Rationale: The correct answer is A: Administer antihistamines as prescribed. Pruritus, or itching, is a common symptom in clients with cirrhosis. Antihistamines can help relieve itching by blocking the effects of histamine. Applying alcohol-based lotions (choice B) can further dry out the skin and exacerbate itching. Encouraging frequent baths with hot water (choice C) can also worsen pruritus by stripping the skin of natural oils. Limiting fluid intake (choice D) is not directly related to managing pruritus in cirrhosis.

A client with diabetes mellitus is admitted with hyperglycemia. What is the priority nursing action?

• A. Administer insulin as prescribed
• B. Encourage fluid intake
• C. Monitor blood glucose levels frequently
• D. Assess for signs of hypoglycemia

Correct Answer: A
Rationale: Administering insulin is the priority nursing action for a client admitted with hyperglycemia due to diabetes mellitus. Insulin helps lower blood glucose levels and prevent further complications associated with hyperglycemia. Encouraging fluid intake is important but not the priority as insulin administration takes precedence to address the immediate hyperglycemic state. Monitoring blood glucose levels frequently is essential but comes after administering insulin to ensure the treatment's effectiveness. Assessing for signs of hypoglycemia is incorrect as the client is admitted with hyperglycemia, which requires raising blood glucose levels, not lowering them further.

A client with foul-smelling drainage from an incision on the upper left arm is admitted with a suspected methicillin-resistant Staphylococcus aureus (MRSA). Which nursing interventions should the nurse include in the plan of care? (Select all that apply.)

• A. Send wound drainage for culture and sensitivity.
• B. Institute contact precautions for staff and visitors.
• C. Use standard precautions and wear a mask.
• D. Monitor the client's white blood cell count.

Correct Answer: B
Rationale: When dealing with a client suspected of having MRSA, the nurse should implement contact precautions to prevent the spread of infection. This includes using gowns and gloves, along with following proper hand hygiene practices. Sending wound drainage for culture and sensitivity may be necessary for diagnostic purposes, but it is not directly related to preventing the spread of infection in this case. Using standard precautions and wearing a mask are not sufficient when dealing with MRSA; contact precautions are specifically required to prevent transmission. Monitoring the client's white blood cell count is important in assessing infection status but is not a primary intervention to prevent the spread of MRSA.

The healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?

• A. Alkalosis
• B. Acidosis
• C. Normal serum pH
• D. Incompatible with life

Correct Answer: C
Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client’s acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.
