Exam Cram NCLEX RN Practice Questions
1. A home care nurse instructs the mother of a 5-year-old child with lactose intolerance about dietary measures for her child. The nurse should tell the mother that it is necessary to provide which dietary supplement in the child's diet?
- A. Fats
- B. Zinc
- C. Protein
- D. Calcium
Correct answer: D
Rationale: In lactose intolerance, the inability to digest lactose, the sugar in dairy products, can lead to calcium deficiency if dairy products are removed from the diet. Calcium is crucial for bone health and other bodily functions, so alternative calcium sources like fortified non-dairy milks or leafy greens must be included to prevent deficiency. While fats and proteins are important nutrients, they are not typically deficient in lactose intolerance. Zinc, although an essential mineral, is not the primary concern in this case.
2. A child presents to the emergency department with colicky abdominal pain in the lower right quadrant. What disorder is suspected based on these symptoms?
- A. Peritonitis
- B. Appendicitis
- C. Intussusception
- D. Hirschsprung's disease
Correct answer: B
Rationale: The child's presentation of colicky abdominal pain in the lower right quadrant is classic for appendicitis. Appendicitis typically presents with localized pain that starts near the umbilicus and then shifts to the right lower quadrant. Peritonitis, on the other hand, is characterized by diffuse abdominal pain, tenderness, and guarding, usually resulting from organ perforation or intestinal obstruction. Intussusception is associated with acute, severe abdominal pain and currant jelly-like stools due to intestinal telescoping. Hirschsprung's disease, which lacks ganglion cells in the colon, manifests with symptoms like constipation, abdominal distension, and foul-smelling, ribbon-like stools.
3. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?
- A. Narrowed QRS complex
- B. Shortened "PR"? interval
- C. Tall peaked "T"? waves
- D. Prominent "U"? waves
Correct answer: C
Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.
4. While working with an obese adolescent, it is important for the nurse to recognize that obesity in adolescents is most often associated with what other behavior?
- A. Sexual promiscuity
- B. Poor body image
- C. Dropping out of school
- D. Drug experimentation
Correct answer: B
Rationale: When addressing obesity in adolescents, it is crucial to consider that poor body image is a common behavior associated with obesity. As adolescents gain weight, they may experience a decrease in self-esteem and a negative perception of their body. This can contribute to a cycle of unhealthy behaviors and impact their overall well-being. The other choices are less commonly associated with obesity in adolescents. Sexual promiscuity may be influenced by various factors unrelated to obesity, dropping out of school is more often linked to academic challenges or social issues, and drug experimentation can stem from a range of influences but is not directly correlated with obesity.
5. The parent of an infant diagnosed with gastroesophageal reflux disease is receiving feeding instructions from the nurse. Which instruction should the nurse give to the parent to assist in reducing the episodes of emesis?
- A. Provide smaller, more frequent feedings.
- B. Burp the infant frequently during feedings.
- C. Thin the feedings by adding water to the formula.
- D. Thicken the feedings by adding rice cereal to the formula.
Correct answer: D
Rationale: Gastroesophageal reflux disease involves the backward flow of gastric contents into the esophagus due to sphincter issues. To reduce episodes of emesis, it is recommended to thicken feedings by adding rice cereal to the formula. This helps to weigh down the contents in the stomach, making regurgitation less likely. Providing smaller, more frequent feedings and burping the infant frequently are beneficial strategies for gastroesophageal reflux. However, in this case, thickening the feedings is the most appropriate intervention. Thinning the feedings by adding water to the formula is not recommended as it can decrease the caloric density of the formula and may not help in reducing reflux.
