1. 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.
2. A client is receiving a continuous infusion of normal saline at 125 ml/hour post abdominal surgery. The client is drowsy and complaining of constant abdominal pain and a headache. Urine output is 800 ml over the past 24h with a central venous pressure of 15 mmHg. The nurse notes respiratory crackle and bounding central pulses. Vital signs: temperature 101.2°F, Heart rate 96 beats/min, Respirations 24 breaths/min, and Blood pressure 160/90 mmHg. Which interventions should the nurse implement first?
- A. Review the last administration of IV pain medication.
- B. Administer a PRN dose of acetaminophen.
- C. Decrease IV fluids to keep the vein open (KVO) rate.
- D. Calculate total intake and output.
Correct answer: C
Rationale: The correct answer is to decrease IV fluids to the keep vein open (KVO) rate. The client is showing signs of fluid volume excess, such as drowsiness, headache, elevated CVP, crackles, bounding pulses, and increased blood pressure. Decreasing the IV fluids will help prevent further fluid overload. Reviewing the last administration of IV pain medication (Choice A) may be necessary but addressing the fluid balance issue is the priority. Administering a PRN dose of acetaminophen (Choice B) may help with the headache but does not address the underlying fluid overload. Calculating total intake and output (Choice D) is important but does not directly address the immediate issue of fluid overload and its associated symptoms.
3. The parents of a child who has been diagnosed with sickle cell anemia ask why their child experiences pain. What is the most likely cause of the pain?
- A. Inflammation of the vessels
- B. Obstructed blood flow
- C. Overhydration
- D. Stress-related headaches
Correct answer: B
Rationale: The correct answer is B: Obstructed blood flow. In sickle cell anemia, the sickle-shaped red blood cells can clump together, obstructing blood flow in the vessels. This obstruction leads to tissue hypoxia (lack of oxygen) and necrosis, causing pain. Choice A, inflammation of the vessels, is not the primary cause of pain in sickle cell anemia. Choice C, overhydration, is unrelated to the pathophysiology of sickle cell anemia. Choice D, stress-related headaches, is not a characteristic symptom of sickle cell anemia.
4. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 52, PaCO2 59, HCO3 33. Which statement describes the most likely cause of the simultaneous increase in both PaO2 and PaCO2?
- A. The client is hyperventilating due to anxiety.
- B. The hypoxic drive was reduced by the oxygen therapy.
- C. The client is experiencing respiratory alkalosis.
- D. The client is experiencing metabolic acidosis.
Correct answer: B
Rationale: Oxygen therapy can reduce the hypoxic drive in COPD patients, leading to increased PaCO2 levels while improving oxygenation (PaO2). In this case, the increase in PaO2 and PaCO2 is due to the reduction of the hypoxic drive by the supplemental oxygen. Choice A is incorrect because hyperventilation would lead to decreased PaCO2. Choice C is incorrect as the ABG values do not indicate respiratory alkalosis. Choice D is incorrect as the ABG values do not support metabolic acidosis.
5. The parents of a child who has had a myringotomy are instructed by the nurse to place the child in which position?
- A. Supine
- B. On the affected side
- C. On the unaffected side
- D. In Trendelenburg's position
Correct answer: B
Rationale: Placing the child on the affected side after a myringotomy facilitates ear drainage. This position helps prevent accumulation of fluids in the ear canal, aiding in the healing process. Placing the child in the supine position (Choice A) or on the unaffected side (Choice C) may not be as effective in promoting drainage. The Trendelenburg's position (Choice D) with the head lower than the body is used for conditions requiring increased venous return, not for post-myringotomy care.
