A renal failure patient with severe hyperkalemia (K+ level 7.2 mEq/L) has just been admitted to the nursing unit. Given the severity of this situation, the nurse should be prepared to administer which intravenous infusion stat?

Correct Answer: B

Rationale: The correct answer is B: Regular insulin infusion, rate dependent on lab values. Insulin drives potassium into cells, lowering serum levels. In this case of severe hyperkalemia, urgent intervention is required. The nurse should administer insulin to lower potassium levels quickly. Options A, C, and D are incorrect as they do not directly address the hyperkalemia. Lactated Ringer solution does not specifically address hyperkalemia. Solu-Medrol is a steroid and Dilaudid is a pain medication, neither of which treat hyperkalemia.

Correct Answer: B

Rationale: The correct answer is B: Liver failure. The symptoms of fatigue, weight gain, and decreased albumin levels are indicative of liver failure. Liver failure can lead to decreased albumin synthesis, causing fluid accumulation in the body leading to swelling in the legs. Chronic kidney disease (A) typically presents with other symptoms like elevated creatinine levels. Congestive heart failure (C) usually presents with symptoms like shortness of breath and edema, but not typically low albumin levels. Hypothyroidism (D) can cause fatigue and weight gain, but it does not directly lead to decreased albumin levels and leg swelling.

Correct Answer: A

Rationale: Ideal body weight is the weight associated with optimal health, not a fixed standard or subjective feeling.

Correct Answer: B

Rationale: Protein-calorie malnutrition manifests as poor wound healing, apathy, and edema due to insufficient protein and energy.

Correct Answer: A

Rationale: Obesity is typically defined as 20% or more above ideal body weight.
