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. The nurse is caring for a newborn with a myelomeningocele. Before surgery, what should the nursing interventions include?

• A. Leaving the lesion uncovered and placing the infant supine
• B. Covering the lesion with a sterile, saline-soaked gauze
• C. Applying lotion to the lesion to keep it moist
• D. Covering the lesion with a dry, sterile gauze

Correct answer: B

Rationale: The correct intervention before surgery for a newborn with a myelomeningocele is to cover the lesion with a sterile, saline-soaked gauze. This helps protect the exposed spinal cord and meninges from infection and damage. Choice A is incorrect because leaving the lesion uncovered can increase the risk of infection. Choice C is incorrect because applying lotion can introduce contaminants to the lesion. Choice D is incorrect because covering the lesion with a dry gauze can lead to adherence of the gauze to the wound, causing trauma upon removal and disrupting the healing process.

3. When caring for a 7-week-old infant with hypothyroidism, the nurse explains that the prevention of what complication is dependent on the administration of oral thyroid replacement therapy and is critical for the child?

• A. Excessive growth
• B. Cognitive impairment
• C. Damage to the nervous system
• D. Damage to the urinary system

Correct answer: B

Rationale: The correct answer is B: Cognitive impairment. The treatment of choice for congenital and acquired hypothyroidism is oral thyroid hormone replacement therapy. Prompt treatment is especially critical in the infant with congenital hypothyroidism to avoid permanent cognitive impairment. Excessive growth (Choice A) is not a common complication of hypothyroidism in infants. Damage to the nervous system (Choice C) and damage to the urinary system (Choice D) are not typically associated with untreated hypothyroidism in infants.

4. The nurse uses a diagram to show that the tetralogy of Fallot involves a combination of four congenital defects. What are the defects?

• A. Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy
• B. Pulmonary stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy
• C. Aortic stenosis, atrial septal defect, overriding aorta, right ventricular hypertrophy
• D. Pulmonary stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy

Correct answer: B

Rationale: The correct answer is B: Pulmonary stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. Tetralogy of Fallot involves these four congenital defects. Choice A is incorrect because it includes aortic stenosis instead of pulmonary stenosis, atrial septal defect instead of ventricular septal defect, and left ventricular hypertrophy instead of right ventricular hypertrophy. Choice C is incorrect as it includes aortic stenosis and atrial septal defect instead of pulmonary stenosis and ventricular septal defect. Choice D is incorrect because it includes aortic hypertrophy instead of overriding aorta.

5. The settings on a client's synchronized intermittent mandatory ventilation (SIMV) are respiratory rate 12 breaths/minute, tidal volume at 600 mL, FiO2 35%, and positive end-expiratory pressure (PEEP) 5 cm H2O. Which assessment finding necessitates immediate intervention by the nurse?

• A. Bilateral crackles in the lung bases.
• B. Low-pressure indicator alarm.
• C. Oxygen saturation of 91%.
• D. Respiratory rate of 18 breaths/minute.

Correct answer: B

Rationale: A low-pressure alarm may indicate a disconnection or leak in the system, which needs immediate intervention. Bilateral crackles in the lung bases may indicate fluid overload but do not require immediate intervention in this case. An oxygen saturation of 91% is concerning but not as urgent as a potential equipment issue. A respiratory rate of 18 breaths/minute is higher than the set rate but may not necessitate immediate intervention unless accompanied by other distress symptoms.
