A client with chronic kidney disease is being evaluated for dialysis. Which laboratory value would be most concerning to the nurse?
- A. Hemoglobin 9.5 g/dL
- B. Potassium 6.2 mEq/L
- C. Creatinine 3.5 mg/dL
- D. BUN 50 mg/dL
Correct Answer: B
Rationale: The correct answer is B: Potassium 6.2 mEq/L. In chronic kidney disease, the kidneys struggle to regulate potassium levels, leading to hyperkalemia. A potassium level of 6.2 mEq/L is dangerously high and can cause life-threatening cardiac arrhythmias. Hemoglobin of 9.5 g/dL may indicate anemia, which is common in chronic kidney disease but is not immediately life-threatening. Creatinine and BUN levels are markers of kidney function; although elevated levels indicate kidney impairment, they are not acutely life-threatening like severe hyperkalemia.

The client with a new colostomy is being taught about colostomy care. Which statement by the client indicates effective learning?
- A. I will change my colostomy bag every day.
- B. I should eat a low-fiber diet.
- C. I need to inspect the stoma daily for color and swelling.
- D. I can skip my colostomy care if I feel well.
Correct Answer: C
Rationale: The correct answer is C because inspecting the stoma daily is crucial in identifying any early signs of complications or infections. Choice A is incorrect because changing the colostomy bag daily is not necessary unless there is a specific reason to do so. Choice B is incorrect as a low-fiber diet is not usually recommended for colostomy care. Choice D is incorrect because colostomy care should be performed regularly regardless of how the client feels.
A client is receiving a blood transfusion and reports chills and back pain. What is the nurse's priority action?
- A. Continue the transfusion at a slower rate
- B. Administer an antipyretic
- C. Stop the transfusion immediately
- D. Notify the healthcare provider
Correct Answer: C
Rationale: When a client receiving a blood transfusion reports chills and back pain, it indicates a possible transfusion reaction. The nurse's priority action is to stop the transfusion immediately. Continuing the transfusion at a slower rate (Choice A) can exacerbate the reaction. Administering an antipyretic (Choice B) may help with fever but does not address the underlying issue of a transfusion reaction. Notifying the healthcare provider (Choice D) is important but should not delay the immediate action of stopping the transfusion to ensure the client's safety.
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.
The nurse is assessing a client who has been receiving total parenteral nutrition (TPN) for several days. Which complication should the nurse monitor for?
- A. Hyperglycemia
- B. Hypoglycemia
- C. Hyponatremia
- D. Hypokalemia
Correct Answer: B
Rationale: The correct answer is B: Hypoglycemia. When a client is receiving total parenteral nutrition (TPN) with a high glucose content, the risk of hypoglycemia is significant due to sudden increases in insulin release in response to the glucose load. The nurse should monitor for signs and symptoms of hypoglycemia such as shakiness, sweating, palpitations, and confusion. Hyperglycemia (choice A) is not typically a complication of TPN as the high glucose content is more likely to cause hypoglycemia. Hyponatremia (choice C) and hypokalemia (choice D) are electrolyte imbalances that can occur in clients receiving TPN, but hypoglycemia is the more common and immediate concern that the nurse should monitor for.
Which structures are located in the subcutaneous layer of the skin?
- A. Sebaceous and sweat glands
- B. Melanin and keratin
- C. Sensory receptors and hair follicles
- D. Adipose cells and blood vessels
Correct Answer: D
Rationale: The correct answer is D: Adipose cells and blood vessels. The subcutaneous layer, also known as the hypodermis, primarily consists of adipose (fat) tissue and blood vessels. Adipose tissue provides insulation, energy storage, and cushioning, while blood vessels supply nutrients and oxygen. Sebaceous and sweat glands are located in the dermis, which is the layer beneath the epidermis. Melanin and keratin are components of the epidermis, responsible for skin color and waterproofing, respectively. Sensory receptors and hair follicles are found in the dermis and extend into the subcutaneous layer but are not exclusive to it.
