Nursing Elites

1. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

2. While caring for the client during the first hour after delivery, the nurse determines that the uterus is boggy and there is vaginal bleeding. What should be the nurse's first action?

• A. Check vital signs.
• B. Massage the fundus.
• C. Offer a bedpan.
• D. Check for perineal lacerations.

Correct answer: B

Rationale: The nurse's first action should be to massage the fundus until it is firm as uterine atony is the primary cause of bleeding in the first hour after delivery. Massaging the fundus helps to stimulate uterine contractions, which can help control the bleeding. Checking vital signs would be important but addressing the primary cause of bleeding takes precedence. Offering a bedpan is not a priority in this situation as the focus should be on managing the postpartum bleeding. Checking for perineal lacerations is also important but not the initial action needed to address the boggy uterus and vaginal bleeding.

3. The parents of a 2-year-old child who had an orchiopexy to correct cryptorchidism are provided with discharge instructions by the nurse. Which statement by the parents indicates the need for further instruction?

• A. I'll check his temperature.
• B. I'll give him medication so he'll be comfortable.
• C. I'll check his voiding to be sure there's no problem.
• D. I'll let him decide when to return to his play activities.

Correct answer: D

Rationale: Cryptorchidism is a condition where one or both testes fail to descend into the scrotal sac. Orchiopexy, a surgical correction, may be required. After surgery, it is crucial to restrict vigorous activities for 2 weeks to promote healing and prevent injury. Allowing the child to decide when to return to play activities may lead to delayed healing and increased risk of injury, as 2-year-olds typically want to be active. Checking the child's temperature, administering analgesics as needed, and monitoring urine output are important postoperative care measures to ensure recovery and detect complications early. Therefore, the statement indicating the need for further instruction is the one related to letting the child decide when to resume play activities.

4. The health care provider writes an order for bacteriologic testing for a patient who has a positive tuberculosis skin test. Which action should the nurse take?

• A. Teach about the reason for the blood tests.
• B. Schedule an appointment for a chest x-ray.
• C. Teach about the need to get sputum specimens for 2 to 3 consecutive days.
• D. Instruct the patient to expectorate three specimens as soon as possible.

Correct answer: C

Rationale: The correct action for the nurse to take is to teach the patient about the need to collect sputum specimens for 2 to 3 consecutive days for bacteriologic testing for M. tuberculosis. It is important to obtain these specimens on different days rather than all at once. Blood tests are not used for tuberculosis testing, so teaching about blood tests is not relevant. While a chest x-ray is important in tuberculosis diagnosis, it is not a bacteriologic test. The appearance on a chest x-ray alone is not sufficient to diagnose TB as other diseases can have similar findings.

5. A patient asks the nurse why they must have a heparin injection. What is the nurse's best response?

• A. Heparin will dissolve clots that you have.
• B. Heparin will reduce the platelets that make your blood clot.
• C. Heparin will work better than warfarin.
• D. Heparin will prevent new clots from developing.

Correct answer: D

Rationale: The correct answer is D: 'Heparin will prevent new clots from developing.' Heparin is an anticoagulant medication that helps prevent the formation of new blood clots. It does not dissolve existing clots (choice A), reduce platelets (choice B), or necessarily work 'better' than warfarin (choice C) but rather functions differently. The primary action of heparin is to prevent the development of new clots, especially in conditions where clot formation is a concern.
