Nursing Elites

1. A nurse is planning care for a client who has chronic kidney disease. Which finding indicates the need for hemodialysis?

• A. BUN 14 mg/dL
• B. Serum potassium 4.2 mEq/L
• C. Serum creatinine 5 mg/dL
• D. Serum calcium 9 mg/dL

Correct answer: C

Rationale: The correct answer is C. A serum creatinine level of 5 mg/dL is significantly elevated and indicates the need for hemodialysis to help filter waste products from the blood. Elevated creatinine levels suggest impaired kidney function and the inability to effectively filter waste from the body. Choices A, B, and D are within normal ranges and do not indicate the need for immediate hemodialysis in a client with chronic kidney disease.

2. A nurse is reviewing the ABG results of a client with chronic emphysema. Which result suggests the need for further treatment?

• A. PaO2 level of 89 mm Hg
• B. PaCO2 level of 55 mm Hg
• C. HCO3 level of 25 mEq/L
• D. pH level of 7.37

Correct answer: B

Rationale: The correct answer is B. A PaCO2 level of 55 mm Hg is elevated, indicating carbon dioxide retention, a common complication of emphysema that necessitates intervention. Elevated PaCO2 can lead to respiratory acidosis, reflecting inadequate ventilation. Choices A, C, and D are within normal ranges. A PaO2 level of 89 mm Hg is acceptable. An HCO3 level of 25 mEq/L falls within the normal range, suggesting adequate compensation. A pH level of 7.37 is also within the normal range, indicating the client's acid-base balance is maintained.

3. An antepartum client is Rh negative and understands that she will receive a RhoGAM injection during her pregnancy. The client asks the nurse if she will also receive a RhoGAM injection after the birth of her baby. The client will receive RhoGAM after the birth if blood tests are:

• A. Mother Rh positive; baby Rh negative
• B. Mother Rh negative; Coombs positive; baby Rh negative
• C. Mother Rh positive; Coombs negative; baby Rh positive
• D. Mother Rh negative; Coombs negative; baby Rh positive

Correct answer: D

Rationale: The correct answer is D. If the baby is Rh positive and the mother is Rh negative, the mother may develop antibodies against the baby's blood. RhoGAM is administered to prevent the mother's immune system from becoming sensitized to Rh-positive blood. Therefore, the mother, who is Rh negative, will receive RhoGAM after birth if the baby is Rh positive and both the mother and baby have negative Coombs tests. Choices A, B, and C are incorrect because they do not match the criteria for RhoGAM administration in this scenario.

4. A nurse is preparing to administer enoxaparin to a client. Which of the following actions should the nurse take?

• A. Aspirate before injecting
• B. Massage the site after injecting
• C. Administer the injection in the abdomen
• D. Inject at a 90-degree angle

Correct answer: C

Rationale: The correct action the nurse should take when administering enoxaparin is to inject the medication in the abdomen subcutaneously. This route ensures proper absorption of the medication. Aspiration is not necessary before injecting enoxaparin as it is a subcutaneous injection, not an intramuscular injection. Massaging the site after injecting should be avoided to prevent bruising. Enoxaparin injections are typically given at a 45 to 90-degree angle, not necessarily at a strict 90-degree angle.

5. A nurse is planning to administer chlorothiazide 20 mg/kg/day PO divided equally and administered twice daily for a toddler who weighs 28.6 lb. How many mL should the nurse administer per dose? (Round to the nearest tenth)

• A. 2.6 mL
• B. 2.2 mL
• C. 3.5 mL
• D. 5.0 mL

Correct answer: A

Rationale: The correct calculation is as follows: The toddler's weight in kg is 13 kg (28.6 lb / 2.2 lb/kg). The total daily dose is 260 mg (20 mg x 13 kg). Therefore, the dose per administration is 130 mg (260 mg / 2). Given the concentration of 250 mg/5 mL, the dose in mL is 2.6 mL (130 mg / (250 mg/5 mL)). Therefore, the nurse should administer 2.6 mL per dose. Choice B, 2.2 mL, is incorrect as it does not reflect the correct calculation. Choices C and D, 3.5 mL and 5.0 mL, are also incorrect and do not align with the accurate dosage calculation based on the given scenario.
