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. With an alert of an internal disaster and the need for beds, the charge nurse is asked to list clients who are potential discharges within the next hour. Which client should the charge nurse select?
- A. An elderly client who has had type 2 diabetes for over 20 years, admitted with diabetic ketoacidosis 24 hours ago
- B. An adolescent admitted the prior night with Tylenol intoxication
- C. A middle-aged client with an internal automatic defibrillator and complaints of 'passing out at unknown times' admitted yesterday
- D. A school-age child diagnosed with suspected bacterial meningitis and was admitted at the change of shifts
Correct answer: A
Rationale: The correct answer is A because a client with diabetic ketoacidosis (DKA) that is being well-managed and has shown improvement within 24 hours is more stable and can be considered for discharge sooner than those with more acute or unstable conditions. Choice B is incorrect as Tylenol intoxication may require further monitoring and intervention. Choice C is incorrect as a client with an automatic defibrillator and episodes of passing out needs careful evaluation and monitoring. Choice D is incorrect as suspected bacterial meningitis is a serious condition that typically requires a longer hospital stay for treatment and observation.
3. What influences health status?
- A. lifestyle choices and community resources
- B. availability of health technology like diagnostic machines
- C. presence of toxic environmental conditions
- D. all of the above
Correct answer: D
Rationale: Health status is influenced by a combination of lifestyle choices, community resources, health technology like diagnostic machines, and environmental conditions. Each of these factors plays a role in determining an individual's overall health. Choice A is correct as lifestyle choices (such as diet, exercise, and smoking habits) and access to community resources (like healthcare facilities, support groups, and recreational spaces) are important determinants of health. Choice B is correct as the availability of health technology, including diagnostic machines, can impact early detection and treatment of health conditions. Choice C is correct as exposure to toxic environmental conditions (such as pollution, contaminated water, or hazardous waste) can have adverse effects on health. Therefore, the correct answer is D because all of these factors collectively influence health status.
4. The nurse is caring for a client on mechanical ventilation. When performing endotracheal suctioning, the nurse will avoid hypoxia by
- A. Inserting a fenestrated catheter with a whistle tip without suction
- B. Completing the suction pass in 30 seconds with a pressure of 150 mm Hg
- C. Hyperoxygenating with 100% O2 for 1 to 2 minutes before and after each suction pass
- D. Minimizing the suction pass to 60 seconds while slowly rotating the lubricated catheter
Correct answer: C
Rationale: Hyperoxygenating the client before and after suctioning helps prevent hypoxia by ensuring adequate oxygen levels during the procedure, which briefly interrupts the client's normal breathing pattern. Choice A is incorrect because inserting a fenestrated catheter with a whistle tip without suction would not prevent hypoxia. Choice B is incorrect as completing the suction pass in 30 seconds with a pressure of 150 mm Hg may lead to hypoxia. Choice D is incorrect as minimizing the suction pass to 60 seconds may not provide enough time for effective suctioning and could lead to hypoxia.
5. As of 2002, the following data was obtained from municipality X: No. of live births - 750, No. of infant deaths - 10, No. of maternal deaths - 6, Total population - 25,000. The 2002 maternal mortality rate of municipality X is:
- A. 15/1000 live births
- B. 12.5/1000 live births
- C. 6/1000 live births
- D. 8/1000 live births
Correct answer: C
Rationale: The maternal mortality rate is calculated as 6 maternal deaths per 1000 live births. The correct answer is C because to calculate the maternal mortality rate, you divide the number of maternal deaths by the number of live births and then multiply by 1000. Choices A, B, and D are incorrect as they do not match the given data on maternal deaths and live births for municipality X.
