NCLEX RN Exam Review Answers
1. The nurse is caring for an infant with cryptorchidism. The nurse anticipates that the most likely diagnostic study to be prescribed would be the one that assesses which item?
- A. Babinski reflex
- B. DNA synthesis
- C. Urinary function
- D. Chromosomal analysis
Correct answer: C
Rationale: Cryptorchidism, also known as undescended testes, may be caused by hormonal deficiency, intrinsic testicular abnormality, or a structural problem. Diagnostic studies for cryptorchidism typically involve assessing urinary function because the kidneys and testes originate from the same embryonic tissue. The Babinski reflex is a test for neurological function and is not relevant to evaluating cryptorchidism. DNA synthesis and chromosomal analysis are not commonly used diagnostic tests for cryptorchidism, as they are unrelated to the disorder's etiology or presentation.
2. When analyzing the results of the urinalysis collected preoperatively from a child with epispadias scheduled for surgical repair, which finding should the nurse most likely expect to note?
- A. Hematuria
- B. Proteinuria
- C. Bacteriuria
- D. Glucosuria
Correct answer: C
Rationale: Epispadias is a congenital defect characterized by the abnormal placement of the urethral orifice of the penis, often on the dorsum. This anatomical anomaly predisposes individuals to bacterial entry into the urinary tract, leading to bacteriuria. Hematuria, proteinuria, and glucosuria are not typically associated with epispadias. Hematuria refers to the presence of blood in the urine, proteinuria indicates protein in the urine, and glucosuria is the presence of glucose in the urine, none of which are commonly seen in epispadias.
3. Septic, anaphylactic, and neurogenic shock are all categorized as:
- A. Hypovolemic shock
- B. Cardiogenic shock
- C. Distributive shock
- D. Obstructive shock
Correct answer: C
Rationale: Septic, anaphylactic, and neurogenic shock are all types of distributive shock. Distributive shock is characterized by a decrease in systemic vascular resistance, leading to poor tissue perfusion. Septic shock is caused by severe infection, anaphylactic shock is an extreme allergic reaction, and neurogenic shock results from damage to the nervous system. Hypovolemic shock (Choice A) is characterized by a decrease in intravascular volume, cardiogenic shock (Choice B) is due to heart failure, and obstructive shock (Choice D) results from obstruction of blood flow. Therefore, the correct categorization for septic, anaphylactic, and neurogenic shock is distributive shock.
4. The patient with chronic pancreatitis will be taught to take the prescribed pancrelipase (Viokase)
- A. at bedtime.
- B. in the morning.
- C. with each meal.
- D. for abdominal pain.
Correct answer: C
Rationale: The correct answer is to take pancrelipase (Viokase) with each meal. Pancrelipase is a pancreatic enzyme replacement medication that helps with the digestion of nutrients. Patients with chronic pancreatitis often have difficulty digesting food properly due to insufficient pancreatic enzyme production. Taking pancrelipase with each meal assists in the breakdown of fats, proteins, and carbohydrates consumed during the meal. Option A ('at bedtime') is incorrect because enzymes should be taken with meals to aid in digestion. Option B ('in the morning') is not ideal as it does not ensure optimal enzyme activity during meals. Option D ('for abdominal pain') is incorrect as pancrelipase is not meant to be taken solely for pain relief but rather to aid in digestion.
5. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?
- A. The bicarbonate level (HCO3) is 31 mEq/L
- B. The arterial oxygen saturation (SaO2) is 92%
- C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
- D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg
Correct answer: D
Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.
