1. A client is admitted to the intensive care unit with diabetes insipidus due to a pituitary gland tumor. Which potential complication should the nurse monitor closely?
- A. Hypokalemia
- B. Ketonuria
- C. Peripheral edema
- D. Elevated blood pressure
Correct answer: A
Rationale: The correct answer is A: Hypokalemia. In diabetes insipidus, there is excessive urination leading to fluid loss, which can result in electrolyte imbalances such as hypokalemia. Monitoring potassium levels is crucial to prevent complications like cardiac arrhythmias. Choices B, C, and D are incorrect. Ketonuria is typically seen in diabetic ketoacidosis, peripheral edema is more commonly associated with conditions like heart failure or kidney disease, and elevated blood pressure is not a direct complication of diabetes insipidus related to a pituitary gland tumor.
2. While eating at a restaurant, a gravid woman begins to choke and is unable to speak. What action should the nurse who witnesses the event take?
- A. Cardiopulmonary resuscitation with uterine tilt
- B. The Heimlich maneuver using chest thrusts
- C. The Heimlich maneuver using subdiaphragmatic thrusts
- D. Call 911 immediately then begin cardiopulmonary resuscitation
Correct answer: C
Rationale: The correct action for the nurse to take when a pregnant woman is choking and unable to speak is to perform the Heimlich maneuver using subdiaphragmatic thrusts. This technique is recommended for a pregnant woman to prevent harm to the fetus. Option A, cardiopulmonary resuscitation with uterine tilt, is not indicated for a choking episode. Option B, the Heimlich maneuver using chest thrusts, can potentially harm the gravid uterus. Option D, calling 911 immediately before providing assistance, can lead to a delay in addressing the immediate choking emergency.
3. Which assessment finding is most indicative of deep vein thrombosis (DVT) in a client’s right leg?
- A. Dorsiflexes the right foot and left foot on command
- B. A 3 by 5 cm ecchymosis area on the right calf
- C. Right calf is 3 cm larger in circumference than the left calf
- D. Bilateral lower extremities have 3+ pitting edema
Correct answer: C
Rationale: The correct answer is C because a significant difference in calf circumference between the legs is a classic sign of DVT. This is due to the obstruction of blood flow in the deep veins of the leg, leading to swelling in the affected limb. Choices A, B, and D are not typical findings of DVT. Choice A describes a neurological response, choice B indicates a bruise on the right calf, and choice D describes pitting edema in both lower extremities, which are not specific signs of DVT.
4. A client with a large pleural effusion undergoes a thoracentesis. Following the procedure, which assessment finding warrants immediate intervention by the nurse?
- A. The client has asymmetrical chest wall expansion
- B. The client complains of pain at the insertion site
- C. The client's chest x-ray indicates decreased pleural effusion
- D. The client's arterial blood gases show pH 7.35, PaO2 85, PaCO2 35, HCO3 26
Correct answer: A
Rationale: Asymmetrical chest wall expansion is a critical finding post-thoracentesis as it may suggest a pneumothorax, requiring immediate intervention to prevent further complications. The other options, such as pain at the insertion site (Choice B), decreased pleural effusion on chest x-ray (Choice C), and normal arterial blood gases within acceptable ranges (Choice D) do not indicate an immediate need for intervention like asymmetrical chest wall expansion does.
5. In what sequence should the nurse prepare the dose of insulin for a client whose finger stick glucose is 210 mg/dl and is receiving a sliding scale dose of short-acting insulin before breakfast?
- A. Clean the vial's rubber stopper with an alcohol swab, withdraw the correct dose of insulin, and then inject air equal to the insulin dose into the vial.
- B. Inject air equal to the insulin dose into the vial, withdraw the correct dose of insulin, and then clean the vial's rubber stopper with an alcohol swab.
- C. Withdraw the correct dose of insulin, inject air equal to the insulin dose into the vial, and then clean the vial's rubber stopper with an alcohol swab.
- D. Clean the vial's rubber stopper with an alcohol swab, inject air equal to the insulin dose into the vial, and then withdraw the correct dose of insulin.
Correct answer: A
Rationale: The correct sequence for preparing a dose of insulin involves ensuring proper aseptic technique. First, clean the vial's rubber stopper with an alcohol swab to prevent contamination. Second, withdraw the correct dose of insulin to be administered. Lastly, inject air equal to the insulin dose into the vial to maintain proper pressure for withdrawing the medication. This sequence ensures the medication is prepared safely and accurately. Choice A is correct as it follows this sequence. Choices B, C, and D present incorrect sequences that may compromise patient safety by not following the correct aseptic technique. Choice B injects air into the vial before withdrawing insulin, which is incorrect. Choice C reverses the order of withdrawing insulin and injecting air. Choice D withdraws the insulin before injecting air, which can affect the pressure inside the vial and lead to inaccurate dosing.
