Nursing Elites

1. A young adult client, admitted to the Emergency Department following a motor vehicle collision, is transfused with 4 units of PRBCs (packed red blood cells). The client's pretransfusion hematocrit is 17%. Which hematocrit value should the nurse expect the client to have after all the PRBCs have been transfused?

• A. 0.19
• B. 0.09
• C. 0.39
• D. 0.29

Correct answer: D

Rationale: The expected increase in hematocrit after transfusion is approximately 3% per unit of PRBCs. Since the client received 4 units, the expected increase would be 4 x 3% = 12%. Therefore, adding this to the pretransfusion hematocrit of 17% would result in an expected post-transfusion hematocrit of 29%. Choice A (0.19) is incorrect as it doesn't consider the incremental increase per unit of PRBCs. Choices B (0.09) and C (0.39) are also incorrect as they do not align with the expected increase in hematocrit following the transfusion of 4 units of PRBCs.

2. A nurse checks the residual volume from a client’s nasogastric tube feeding before administering an intermittent tube feeding and finds 35 mL of gastric contents. What should the nurse do before administering the prescribed 100 mL of formula to the client?

• A. Pour the residual volume into the nasogastric tube through a syringe with the plunger removed
• B. Discard the residual volume properly and record it as output on the client’s fluid balance record
• C. Dilute the residual volume with water and inject it into the nasogastric tube, applying pressure on the plunger
• D. Mix the residual volume with the formula and pour it into the nasogastric tube, using a syringe without a plunger

Correct answer: A

Rationale: After checking the residual feeding contents, the nurse should pour the residual volume back into the stomach by removing the syringe bulb or plunger and then pouring the gastric contents, using the syringe, into the nasogastric tube. This helps ensure that the residual volume is reintroduced into the client's gastrointestinal tract. Option B is incorrect because discarding the residual volume without reinstilling it into the stomach can lead to inaccurate medication administration and potential electrolyte imbalances. Option C is incorrect as diluting the residual volume with water and injecting it under pressure can cause aspiration or discomfort for the client. Option D is incorrect because mixing the residual volume with the formula can alter the prescribed dosage and consistency, potentially affecting the client's nutritional intake and causing complications.

3. After a lumbar puncture, into which position does the nurse assist the client?

• A. Flat
• B. Semi-Fowler
• C. Side-lying with the head of the bed elevated
• D. Sitting up in a recliner with the feet elevated

Correct answer: A

Rationale: After a lumbar puncture, the client should be positioned flat. This position helps prevent post-procedure spinal headaches and cerebrospinal fluid leakage. Keeping the client flat for up to 12 hours is crucial in minimizing these risks. Choices B, C, and D are incorrect because elevating the head of the bed or sitting up can increase the risk of complications by altering the pressure in the spinal canal, potentially leading to headaches and fluid leakage.

4. The client with chronic kidney disease (CKD) is being taught about the necessary sodium restriction in the diet to prevent edema and hypertension. Which statement by the client indicates more teaching is needed?

• A. I am thrilled that I can continue to eat fast food.
• B. I will cut out bacon with my eggs every morning.
• C. My cooking style will change by not adding salt.
• D. I will probably lose weight by cutting out potato chips.

Correct answer: A

Rationale: Choice A, 'I am thrilled that I can continue to eat fast food,' indicates a lack of understanding as fast food is typically high in sodium, which is detrimental for individuals with CKD. The client should be advised to avoid fast food due to its high sodium content. Choices B, C, and D demonstrate a good understanding of the need for sodium restriction in the diet to prevent complications associated with CKD. Cutting out bacon, avoiding salt in cooking, and eliminating high-sodium snacks like potato chips are all positive steps towards managing CKD.

5. A patient is taking a thiazide diuretic and reports anorexia and fatigue. The nurse suspects which electrolyte imbalance in this patient?

• A. Hypercalcemia
• B. Hypocalcemia
• C. Hyperkalemia
• D. Hypokalemia

Correct answer: D

Rationale: The correct answer is D: Hypokalemia. Thiazide diuretics lead to potassium loss, potentially causing hypokalemia. Anorexia and fatigue are common manifestations of hypokalemia. Hypercalcemia (choice A) and hypocalcemia (choice B) are not directly associated with thiazide diuretics. Hyperkalemia (choice C) is less likely than hypokalemia to be caused by thiazide diuretics.
