Community Health HESI Study Guide
1. In reviewing the assessment data of a client suspected of having diabetes insipidus, the nurse expects which of the following after a water deprivation test?
- A. Increased edema and weight gain
- B. Unchanged urine specific gravity
- C. Rapid protein excretion
- D. Decreased blood potassium
Correct answer: B
Rationale: After a water deprivation test in a client suspected of having diabetes insipidus, the nurse would expect the urine specific gravity to remain unchanged. This occurs because in diabetes insipidus, the kidneys are unable to concentrate urine, leading to a low urine specific gravity even after water deprivation. Choices A, C, and D are incorrect. Increased edema and weight gain are not typical findings in diabetes insipidus. Rapid protein excretion is not directly related to the condition, and decreased blood potassium is not a common outcome of a water deprivation test for diabetes insipidus.
2. 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.
3. A client requires bed rest and has a prescription for anti-embolic stockings. Which of the following actions should the nurse take?
- A. Apply the stockings with the creases on the front of the leg.
- B. Apply the stockings while the client's legs are in a dependent position.
- C. Remove the stockings at least once per shift.
- D. Remove the stockings while the client is sitting in a reclining chair.
Correct answer: C
Rationale: The correct action for the nurse to take is to remove the anti-embolic stockings at least once per shift. This is essential to assess the client's circulation and skin integrity. Option A is incorrect because the stockings should be applied without creases to ensure proper compression. Option B is incorrect as the stockings should be applied when the client's legs are elevated, not in a dependent position. Option D is incorrect as removing the stockings while the client is sitting in a reclining chair is not necessary and does not provide the appropriate assessment opportunity.
4. The RN at a migrant health center notes an increased incidence of dermatitis in seasonal farm workers at a local fruit farm. In response to this finding, what is the most important information for the RN to obtain as part of the community assessment?
- A. Availability of clean fresh water to wash hands after work.
- B. Proper housing
- C. Access to health care services
- D. Access to transportation
Correct answer: A
Rationale: The correct answer is A: Availability of clean fresh water to wash hands after work. Proper hand hygiene, including washing hands with clean water, is crucial in preventing dermatitis, especially in farm workers who are exposed to potential irritants in their work environment. While proper housing (choice B), access to health care services (choice C), and access to transportation (choice D) are important factors in overall community health, they are not directly linked to preventing dermatitis in this scenario.
5. The mother of a teenager is told that her son has recently been found stealing from other students at school. The mother's response is, 'I cannot think about that today.' The nurse determines that this mother is using which defense mechanism?
- A. Suppression
- B. Repression
- C. Sublimation
- D. Undoing
Correct answer: A
Rationale: The correct answer is A, Suppression. Suppression involves a conscious effort to avoid dealing with distressing thoughts or feelings. In this case, the mother is consciously choosing not to think about her son's behavior. Choice B, Repression, involves unconsciously blocking out distressing thoughts or feelings. Choice C, Sublimation, is the channeling of unacceptable impulses into socially acceptable behaviors, which is not demonstrated in this scenario. Choice D, Undoing, is a defense mechanism where a person tries to undo or reverse a negative thought or action by performing a contrary behavior, which is not applicable here.
