Correct Answer: D

Rationale: The correct instruction for a client with DVT is to elevate the affected extremity when in bed. Elevation helps reduce swelling by promoting venous return. Limiting fluid intake could lead to dehydration and is not recommended. Massaging the affected extremity can dislodge a clot, leading to serious complications. Applying cold packs can cause vasoconstriction and should be avoided in DVT.

Correct Answer: C

Rationale: The correct answer is C: Monitor the client's respiratory rate. When a client is receiving opioid analgesics, the priority assessment is monitoring respiratory rate. Opioids can cause respiratory depression, so it is crucial to assess the client's breathing to detect any signs of respiratory distress promptly. Checking the client's blood pressure (Choice A) and urinary output (Choice B) are important assessments too, but they are not the priority when compared to ensuring adequate respiratory function. Assessing the client's pain level (Choice D) is essential for overall care but is not the priority assessment when the client is on opioids, as respiratory status takes precedence.

Correct Answer: D

Rationale: The correct instruction the nurse should include is to rotate injection sites within the same anatomical region. This practice helps reduce the risk of lipodystrophy, a condition characterized by fatty tissue changes due to repeated insulin injections in the same spot. By rotating sites, the client ensures better insulin absorption and prevents localized skin changes. Injecting air into the vial before withdrawing insulin (Choice A) is unnecessary and not recommended. Drawing up short-acting insulin before long-acting insulin (Choice B) is not a standard practice and can lead to errors in dosing. Storing unopened insulin vials in the freezer (Choice C) is incorrect as insulin should be stored in the refrigerator, not the freezer, to maintain its effectiveness.

Correct Answer: C

Rationale: A serum potassium level of 3.2 mEq/L indicates hypokalemia, a complication that should be reported in clients receiving TPN. Hypokalemia can lead to serious cardiac and neuromuscular complications. The other options are within normal ranges and do not indicate immediate concerns for a client receiving TPN. A blood glucose level of 130 mg/dL, serum sodium level of 140 mEq/L, and platelet count of 250,000/mm³ are all considered normal values and do not require immediate intervention.

Correct Answer: C

Rationale: The correct answer is to limit saturated fat intake to 7% of daily calories. This recommendation is crucial for clients with hypertension to lower cholesterol levels and promote heart health. Choice A, limiting sodium intake to 4 grams per day, is important for hypertension but not the best recommendation compared to limiting saturated fats. Choice B, limiting protein intake to 80 grams per day, is not a primary dietary concern for hypertension. Choice D, limiting fluid intake to 1,500 mL per day, is not a standard recommendation for hypertension management.
