Nursing Elites

1. A nurse is assessing a client who has diabetic ketoacidosis (DKA). Which of the following laboratory findings should the nurse expect?

• A. Blood glucose 120 mg/dL
• B. pH 7.32
• C. HCO3 25 mEq/L
• D. PaCO2 48 mm Hg

Correct answer: B

Rationale: The correct answer is B. A pH of 7.32 indicates metabolic acidosis, which is a hallmark of diabetic ketoacidosis (DKA). In DKA, blood glucose levels are typically elevated, bicarbonate levels are often low, and there is a compensatory respiratory response leading to a decrease in PaCO2. Option A is incorrect because a blood glucose level of 120 mg/dL is within the normal range and not indicative of DKA. Option C is incorrect because an HCO3 level of 25 mEq/L is not typically seen in DKA where bicarbonate levels are usually lower. Option D is incorrect because a PaCO2 of 48 mm Hg would not be expected in DKA; it would typically be lower due to compensatory respiratory alkalosis.

2. A nurse is admitting a client who has tuberculosis and a productive cough. Which of the following types of isolation precautions should the nurse initiate for the client?

• A. Contact
• B. Droplet
• C. Protective
• D. Airborne

Correct answer: D

Rationale: The correct answer is D: Airborne. Tuberculosis is spread through small droplets that remain airborne for longer periods, hence requiring airborne precautions. Choice A - Contact precautions are used for diseases spread by direct or indirect contact. Choice B - Droplet precautions are for diseases transmitted by large respiratory droplets that can travel short distances. Choice C - Protective isolation is not necessary for tuberculosis, as it is not spread through contact with the client.

3. A client is in active labor and is receiving an epidural for pain relief. Which of the following should the nurse monitor as the priority?

• A. Fetal heart rate
• B. Client's blood pressure
• C. Client's respiratory rate
• D. Client's pain level

Correct answer: B

Rationale: The most common side effect of an epidural is hypotension, which can compromise placental perfusion. Monitoring the client's blood pressure is the priority to ensure maternal and fetal well-being. Fetal heart rate is important but monitoring the client's blood pressure takes precedence due to the risk of hypotension. Respiratory rate and pain level monitoring are also important but not the priority in this scenario.

4. A nurse is caring for a newborn who has a blood glucose level of 45 mg/dL. Which of the following actions should the nurse take?

• A. Encourage the mother to breastfeed the newborn
• B. Gavage feed 60 mL (2 oz) of glucose water
• C. Administer 10 mL of D5W via IV
• D. Recheck the glucose level in 2 hours

Correct answer: A

Rationale: Encouraging the mother to breastfeed the newborn is the most appropriate action in this scenario. Breastfeeding can quickly raise blood glucose levels in newborns. A blood glucose level of 45 mg/dL is often acceptable in newborns, but close monitoring is necessary. Gavage feeding with glucose water or administering D5W via IV may not be necessary at this point and could lead to potential risks of overfeeding or hypoglycemia. Rechecking the glucose level in 2 hours may delay necessary intervention, as breastfeeding can promptly address the low blood glucose levels.

5. A client has developed a pulmonary embolism. Which of the following interventions should the nurse implement first?

• A. Administer oxygen
• B. Prepare the client for a thoracentesis
• C. Elevate the client’s lower extremities
• D. Administer anticoagulant therapy

Correct answer: A

Rationale: Administering oxygen is the priority intervention for a client with a pulmonary embolism. Pulmonary embolism can lead to impaired gas exchange, causing hypoxemia. Administering oxygen helps to maintain adequate oxygenation levels. Thoracentesis is not indicated for a pulmonary embolism, as it is a procedure to remove fluid or air from the pleural space, not a treatment for embolism. Elevating the client's lower extremities is not a priority in the management of a pulmonary embolism. Administering anticoagulant therapy is important in the treatment of pulmonary embolism to prevent further clot formation, but it is not the first intervention. Oxygen administration takes precedence to address the immediate oxygenation needs of the client.
