1. In planning care for a 7-year-old boy with diabetes insipidus, what is the priority nursing diagnosis?
- A. Deficient fluid volume related to dehydration
- B. Excess fluid volume related to edema
- C. Deficient knowledge related to fluid intake regimen
- D. Imbalanced nutrition, more than body requirements related to excess weight
Correct answer: A
Rationale: The priority nursing diagnosis for a 7-year-old boy with diabetes insipidus is deficient fluid volume related to dehydration. Diabetes insipidus leads to excessive urination and fluid loss, which can result in dehydration. This diagnosis should take precedence as restoring fluid balance is crucial in managing this condition. Choices B, C, and D are less of a priority in this case. Excess fluid volume related to edema is not typically associated with diabetes insipidus. Deficient knowledge about fluid intake and imbalanced nutrition related to excess weight may be important but addressing the dehydration and fluid volume deficit is the most critical aspect in the immediate care of a child with diabetes insipidus.
2. What should be assessed in an infant diagnosed with hypertrophic pyloric stenosis?
- A. Diarrhea after each feeding
- B. Gastric pain and vigorous crying
- C. Poor appetite due to poor sucking reflex
- D. An olive-shaped mass right of the midline
Correct answer: D
Rationale: In hypertrophic pyloric stenosis, an olive-shaped mass can often be palpated in the infant's abdomen, which is a hallmark sign of this condition. This mass is located in the right upper quadrant of the abdomen, right of the midline. Choices A, B, and C are incorrect because while infants with hypertrophic pyloric stenosis may experience vomiting (not diarrhea), gastric pain, and irritability, and have feeding difficulties, the key assessment finding specific to this condition is the palpable olive-shaped mass in the abdomen.
3. When admitting a 5-month-old who has vomited 9 times in the past 6 hours, what should the healthcare provider observe for signs of which overall imbalance?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Increased serum hemoglobin levels
- D. Decreased serum potassium levels
Correct answer: B
Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.
4. The healthcare provider is caring for a client with a wound infection. Which type of dressing is most appropriate to use to promote healing by secondary intention?
- A. Dry gauze dressing
- B. Wet-to-dry dressing
- C. Transparent film dressing
- D. Hydrocolloid dressing
Correct answer: D
Rationale: Hydrocolloid dressings are ideal for promoting healing by secondary intention in wound infections. These dressings create a moist environment that supports autolytic debridement and facilitates the healing process. Dry gauze dressings (Option A) may lead to adherence, causing trauma upon removal and disrupting the wound bed. Wet-to-dry dressings (Option B) are primarily used for mechanical debridement and can be painful during dressing changes. Transparent film dressings (Option C) are more suitable for superficial wounds with minimal exudate and are not typically used for wound infections requiring healing by secondary intention.
5. What is a procedure for using ultrasonic sound waves to create a picture of an embryo or fetus?
- A. Phenotype
- B. Sonogram
- C. Genotype
- D. Alpha-fetoprotein (AFP) assay
Correct answer: B
Rationale: A sonogram, also known as an ultrasound, is a procedure that utilizes sound waves to generate images of a developing embryo or fetus. This imaging technique is commonly used in prenatal care to monitor fetal development and identify any potential abnormalities. Choices A, C, and D are incorrect because a phenotype refers to an individual's observable traits resulting from genetic and environmental influences, a genotype is an individual's genetic makeup, and an alpha-fetoprotein (AFP) assay is a blood test used to screen for certain birth defects.
