1. In evaluating a 10-year-old child with meningitis suspected of having diabetes insipidus, which finding is indicative of diabetes insipidus?
- A. Decreased urine specific gravity.
- B. Elevated urine glucose.
- C. Decreased serum potassium.
- D. Increased serum sodium.
Correct answer: A
Rationale: Diabetes insipidus is characterized by the kidneys' inability to concentrate urine, leading to decreased urine specific gravity. This results in the excretion of large volumes of dilute urine, causing a decrease in urine specific gravity. Therefore, when evaluating a suspected case of diabetes insipidus, a finding of decreased urine specific gravity is indicative of this condition.
2. A client who is receiving heparin therapy has an activated partial thromboplastin time (aPTT) of 90 seconds. What action should the nurse take?
- A. Increase the heparin infusion rate.
- B. Notify the healthcare provider.
- C. Apply pressure to the injection site.
- D. Administer protamine sulfate.
Correct answer: B
Rationale: An activated partial thromboplastin time (aPTT) of 90 seconds is elevated, indicating a risk of bleeding. The appropriate action for the nurse is to notify the healthcare provider. Increasing the heparin infusion rate can further elevate the aPTT, leading to an increased risk of bleeding. Applying pressure to the injection site is not relevant in this situation. Administering protamine sulfate is used to reverse the effects of heparin in cases of overdose or bleeding, but it is not the initial action for an elevated aPTT.
3. The client with newly diagnosed osteoporosis is being taught by the nurse about dietary modifications. Which instruction should the nurse include?
- A. Increase your intake of high-calcium foods.
- B. Limit your intake of vitamin D-rich foods.
- C. Avoid foods high in phosphorus.
- D. Increase your intake of high-sodium foods.
Correct answer: A
Rationale: Increasing the intake of high-calcium foods is essential for improving bone density and managing osteoporosis. Calcium is a key mineral necessary for bone health, and individuals with osteoporosis often need higher levels of calcium to help strengthen their bones and prevent further bone loss. Therefore, advising the client to increase their intake of high-calcium foods is the most appropriate dietary modification to support their bone health.
4. A client's telemetry monitor indicates the sudden onset of ventricular fibrillation. Which assessment finding should the nurse anticipate?
- A. Bounding erratic pulse.
- B. Regularly irregular pulse.
- C. Thready irregular pulse.
- D. No palpable pulse.
Correct answer: D
Rationale: Ventricular fibrillation is a life-threatening arrhythmia characterized by chaotic, asynchronous contractions of the ventricles, resulting in ineffective cardiac output. This leads to the absence of a palpable pulse. Nurses should be prepared to initiate immediate interventions such as defibrillation to restore normal cardiac rhythm in a client experiencing ventricular fibrillation.
5. A healthcare professional is assessing a client with severe dehydration. Which finding indicates a need for immediate intervention?
- A. Heart rate of 110 beats per minute.
- B. Blood pressure of 90/60 mm Hg.
- C. Urine output of 20 ml/hour.
- D. Dry mucous membranes.
Correct answer: C
Rationale: A urine output of 20 ml/hour indicates severe dehydration and impaired renal function. This finding suggests a critical state where the kidneys are conserving water, leading to reduced urine output. Immediate intervention is required to restore fluid balance and prevent further complications associated with severe dehydration. Choice A, a heart rate of 110 beats per minute, may indicate dehydration but is not as severe as the critically low urine output. Choice B, a blood pressure of 90/60 mm Hg, can be seen in dehydration but is not as concerning as the extremely low urine output. Choice D, dry mucous membranes, is a common sign of dehydration but does not require immediate intervention compared to the severely reduced urine output.
