Exam Cram NCLEX RN Practice Questions
1. The clinic nurse is obtaining data about a child with a diagnosis of lactose intolerance. Which data should the nurse expect to obtain on assessment?
- A. Reports of frothy stools and diarrhea
- B. Reports of foul-smelling ribbon stools
- C. Reports of profuse, watery diarrhea and vomiting
- D. Reports of diffuse abdominal pain unrelated to meals or activity
Correct answer: A
Rationale: Lactose intolerance commonly presents with frothy stools and diarrhea due to the inability to digest lactose. Other symptoms include abdominal distension, crampy abdominal pain, and excessive flatus. Foul-smelling ribbon stools are indicative of Hirschsprung's disease, not lactose intolerance. Profuse, watery diarrhea and vomiting are more characteristic of celiac disease. Diffuse abdominal pain unrelated to meals or activity is a typical symptom of irritable bowel syndrome, not lactose intolerance.
2. 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.
3. A mother has recently been informed that her child has Down syndrome. You will be assigned to care for the child at shift change. Which of the following characteristics is not associated with Down syndrome?
- A. Simian crease
- B. Brachycephaly
- C. Oily skin
- D. Hypotonicity
Correct answer: C
Rationale: Individuals with Down syndrome commonly have certain physical characteristics, such as a simian crease (single transverse palmar crease), brachycephaly (shortened front-to-back skull dimension), and hypotonicity (low muscle tone). Oily skin is not a characteristic associated with Down syndrome; instead, individuals with Down syndrome often have dry skin. Therefore, oily skin is the correct answer in this context.
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. When is cleft palate repair usually performed in children?
- A. A cleft palate cannot be repaired in children.
- B. Repair is usually performed by age 8 weeks.
- C. Repair is usually performed by 2 months of age.
- D. Repair is usually performed between 6 months and 2 years.
Correct answer: D
Rationale: Cleft palate repair timing is individualized based on the severity of the deformity and the child's size. Typically, cleft palate repair is performed between 6 months and 2 years of age. This age range allows for optimal outcomes and is often done before 12 months to promote normal speech development. Early closure of the cleft palate helps to facilitate speech development. Options A, B, and C are incorrect because a cleft palate can be repaired in children, and repair is usually performed between 6 months and 2 years of age, not at 8 weeks or 2 months.
