Fundamentals of Nursing HESI
1. In planning care for a premature infant with respiratory distress syndrome, nursing actions are based on the fact that the most likely cause of this problem stems from the infant's inability to
- A. Stabilize alveolar surface tension
- B. Maintain alveolar surface tension
- C. Promote normal pulmonary blood flow
- D. Regulate intra-cardiac pressure
Correct answer: B
Rationale: The correct answer is B: Maintain alveolar surface tension. Respiratory distress syndrome in premature infants is often caused by a deficiency in surfactant, a substance that helps maintain alveolar surface tension. Without adequate surfactant, the alveoli collapse, making it difficult for the infant to oxygenate effectively. Choices A, C, and D are incorrect because stabilizing alveolar surface tension is not the issue, promoting normal pulmonary blood flow and regulating intra-cardiac pressure are not directly related to the pathophysiology of respiratory distress syndrome in premature infants.
2. A client with ulcerative colitis is experiencing frequent diarrhea. What is the priority nursing diagnosis?
- A. Risk for impaired skin integrity
- B. Fluid volume deficit
- C. Imbalanced nutrition: less than body requirements
- D. Activity intolerance
Correct answer: B
Rationale: The correct answer is B: Fluid volume deficit. In a client with ulcerative colitis experiencing frequent diarrhea, the priority nursing diagnosis is addressing the potential fluid volume deficit due to significant fluid loss. Maintaining adequate hydration is crucial to prevent complications associated with dehydration. While choices A, C, and D can also be concerns for a client with ulcerative colitis, addressing fluid volume deficit takes precedence as it directly impacts the client's physiological stability and can lead to serious complications if not managed promptly.
3. A nurse is providing teaching to an older adult client who has constipation. Which of the following statements should the nurse include in the teaching?
- A. Sit on the toilet 30 minutes after eating a meal.
- B. Increase your fluid intake to help with bowel movements.
- C. Exercise regularly to improve bowel function.
- D. Consume more high-fiber foods to prevent constipation.
Correct answer: A
Rationale: The correct statement the nurse should include in the teaching is to 'Sit on the toilet 30 minutes after eating a meal.' This advice can help establish a regular bowel routine and improve bowel movement. Option B, 'Increase your fluid intake to help with bowel movements,' while important, is not specific to the time after eating and does not directly address the need for establishing a routine. Option C, 'Exercise regularly to improve bowel function,' is also important but does not address the timing of bowel movements. Option D, 'Consume more high-fiber foods to prevent constipation,' is beneficial for preventing constipation but does not address the timing aspect related to bowel movements.
4. The nurse is providing care for a newborn who was delivered vaginally assisted by forceps. The nurse observes red marks on the head with swelling that does not cross the suture line. Which condition should the nurse document in the medical record?
- A. Caput succedaneum
- B. Hydrocephalus
- C. Cephalhematoma
- D. Microcephaly
Correct answer: C
Rationale: The correct answer is Cephalhematoma. Cephalhematoma is a collection of blood between the skull bone and periosteum that does not cross the suture line. It often occurs due to birth trauma, such as forceps delivery, leading to localized swelling. Caput succedaneum (Choice A) is diffuse swelling of the scalp that may cross suture lines and is typically present at birth. Hydrocephalus (Choice B) is an abnormal accumulation of cerebrospinal fluid within the brain's ventricles. Microcephaly (Choice D) is a condition characterized by a smaller than average head size and may be present at birth or develop later in infancy.
5. A teenaged client, a heroin addict, is admitted to the unit for detoxification. What intervention is most important for the nurse to initiate during the first 24 hours after admission?
- A. Assign the client to a teen support group.
- B. Assess intake and output.
- C. Monitor for wheezing and apnea.
- D. Limit visitors to family members only.
Correct answer: B
Rationale: Assessing intake and output is crucial during the first 24 hours after admission for detoxification. This helps the nurse monitor the client's hydration status and kidney function as the body goes through withdrawal from heroin. Option A is incorrect because joining a support group is beneficial but may not be the priority in the initial phase of detoxification. Option C, monitoring for wheezing and apnea, is important but not the most critical intervention during the first 24 hours. Option D, limiting visitors to family members only, is not directly related to the immediate needs of assessing intake and output.
