1. Which laboratory results should the nurse anticipate to be abnormal in a child with hemophilia?

• A. Prothrombin time
• B. Bleeding time
• C. Platelet count
• D. Partial thromboplastin time

Correct answer: D

Rationale: In a child with hemophilia, the nurse should anticipate an abnormality in the partial thromboplastin time (PTT) due to the deficiency in clotting factors. Prothrombin time, bleeding time, and platelet count are typically normal in hemophilia. Prothrombin time measures the extrinsic pathway of coagulation and is not affected in hemophilia. Bleeding time assesses platelet function, which is normal in hemophilia as the issue lies with clotting proteins, not platelets. Platelet count is also expected to be normal unless there is another underlying condition affecting platelet production or function.

2. A client with chronic heart failure is experiencing dyspnea and has an oxygen saturation of 88%. Which position is most appropriate to improve oxygenation?

• A. Supine with legs elevated
• B. High Fowler's position
• C. Prone with pillows under the chest
• D. Side-lying with head flat

Correct answer: B

Rationale: The correct answer is B: High Fowler's position. High Fowler's position is the most appropriate for a client with chronic heart failure experiencing dyspnea and low oxygen saturation. This position helps improve lung expansion and oxygenation by maximizing chest expansion and allowing better ventilation. Choice A, supine with legs elevated, may worsen dyspnea by reducing lung expansion. Choice C, prone with pillows under the chest, is not suitable for a client experiencing dyspnea as it may further compromise breathing. Choice D, side-lying with head flat, does not facilitate optimal lung expansion and is not the best choice for improving oxygenation in this scenario.

3. Laboratory findings indicate that a client’s serum potassium level is 2.5 mEq/L. What action should the nurse take?

• A. Administer potassium supplements orally.
• B. Increase the client's dietary potassium intake.
• C. Inform the healthcare provider of the need for potassium replacement.
• D. Monitor the client's ECG continuously.

Correct answer: C

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. In this situation, it is essential for the nurse to inform the healthcare provider promptly about the need for potassium replacement. Administering potassium supplements orally or increasing dietary potassium intake is not appropriate in cases of critically low potassium levels as immediate and precise replacement is necessary. Monitoring the client's ECG continuously is important in severe cases of hypokalemia, but the priority action should be to inform the healthcare provider for further management and treatment.

4. A client with Parkinson's disease is experiencing difficulty swallowing. Which intervention should the nurse implement to prevent aspiration?

• A. Encourage the client to eat quickly.
• B. Provide a straw for liquids.
• C. Place the client in an upright position during meals.
• D. Offer thin liquids.

Correct answer: C

Rationale: Placing the client in an upright position during meals is the correct intervention to prevent aspiration in a client with Parkinson's disease. This position helps facilitate swallowing and reduces the risk of aspiration. Choice A is incorrect because encouraging the client to eat quickly can increase the risk of choking and aspiration. Choice B is not the best option as straws may not prevent aspiration effectively. Choice D is incorrect as thin liquids can actually increase the risk of aspiration in individuals with swallowing difficulties.

5. What assessment findings should lead the nurse to suspect Down syndrome in a newborn?

• A. Hypertonia and dark skin
• B. Low-set ears and a simian crease
• C. Inner epicanthal folds and a high, domed forehead
• D. Long, thin fingers and excessive hair

Correct answer: B

Rationale: The correct answer is B: 'Low-set ears and a simian crease.' These are key physical characteristics commonly seen in newborns with Down syndrome. Low-set ears, along with a simian crease (a single palmar crease), are indicative of Down syndrome. Choices A, C, and D are incorrect because hypertonia, dark skin, inner epicanthal folds, a high, domed forehead, long, thin fingers, and excessive hair are not specific features associated with Down syndrome in newborns. Therefore, the presence of low-set ears and a simian crease should raise suspicion for Down syndrome and prompt further evaluation.
