Nursing Elites

1. A 13-year-old girl, diagnosed with diabetes mellitus Type 1 at the age of 9, is admitted to the hospital in diabetic ketoacidosis. Which occurrence is the most likely cause of the ketoacidosis?

• A. Ate an extra peanut butter sandwich before gym class
• B. Incorrectly drew up and administered too much insulin
• C. Was not hungry, so she skipped eating lunch
• D. Has had a cold and ear infection for the past two days

Correct answer: B

Rationale: The correct answer is B. Incorrect insulin administration is a common cause of diabetic ketoacidosis. Administering too much insulin can lead to uncontrolled hyperglycemia, where the body starts breaking down fat for energy, resulting in the production of ketones. Choices A, C, and D are less likely to directly cause diabetic ketoacidosis. Eating an extra peanut butter sandwich, skipping lunch, or having a cold and ear infection would not directly lead to the metabolic derangements seen in diabetic ketoacidosis.

2. A client who received multiple antihypertensive medications experiences syncope due to a drop in blood pressure to 70/40. What is the rationale for the nurse’s decision to hold the client’s scheduled antihypertensive medication?

• A. Increased urinary clearance of the multiple medications has led to diuresis and lowered the blood pressure.
• B. The antagonistic interaction among the various blood pressure medications has reduced their effectiveness.
• C. The additive effect of multiple medications has caused the blood pressure to drop too low.
• D. The synergistic effect of the multiple medications has resulted in drug toxicity and resulting hypotension.

Correct answer: C

Rationale: The correct answer is C. When a client experiences syncope due to a significant drop in blood pressure after receiving multiple antihypertensive medications, the additive effect of these medications can cause the blood pressure to drop excessively. This additive effect can lead to hypotension, which is why the nurse decided to hold the client's scheduled antihypertensive medication. Choices A, B, and D provide incorrect rationales. Choice A mentions diuresis, which is not directly related to the drop in blood pressure due to additive medication effects. Choice B refers to an antagonistic interaction reducing effectiveness, which is not applicable in this scenario. Choice D talks about a synergistic effect leading to drug toxicity, which is not the cause of the sudden drop in blood pressure observed in the client.

3. The healthcare provider prescribes potassium chloride 25 mEq in 500 ml D5W to infuse over 6 hours. The available 20 ml vial of potassium chloride is labeled '10 mEq/5 ml.' How many ml of potassium chloride should the nurse add to the IV fluid?

• A. 12.5
• B. 5
• C. 10
• D. 20

Correct answer: B

Rationale: To prepare 25 mEq of potassium chloride for the infusion, the nurse should add 5 ml of the 10 mEq/5 ml solution. This concentration provides the required amount of potassium chloride without exceeding the needed volume. Choice A would result in 12.5 mEq, which exceeds the prescribed amount. Choices C and D are incorrect as they do not align with the correct calculation based on the vial concentration.

4. When lactulose (Cephulac) 30 ml QID is prescribed for a male client with advanced cirrhosis, and he complains that it causes diarrhea, what action should the nurse take in response to the client’s statement?

• A. Explain that diarrhea is expected, but the drug reduces ammonia levels
• B. Document that the client is non-compliant with his treatment plan
• C. Tell the client to be concerned about more significant side effects of this drug
• D. Obtain a prescription for loperamide (Imodium) 4mg PO PRN diarrhea

Correct answer: A

Rationale: The correct answer is A. Diarrhea is an expected side effect of lactulose when used to reduce ammonia levels in cirrhosis. It helps in decreasing the absorption of ammonia in the colon, thereby reducing its levels in the blood. Option B is incorrect because it is essential for the nurse to educate the client about the expected side effects of the medication rather than assuming non-compliance. Option C is incorrect as it instills unnecessary fear in the client by suggesting more significant side effects without addressing the current concern. Option D is incorrect as loperamide should not be given automatically for diarrhea caused by lactulose, as the diarrhea is a therapeutic effect of the medication in this context.

5. When washing soiled hands, what should the nurse do after wetting the hands and applying soap?

• A. Rub hands palm to palm
• B. Interlace the fingers
• C. Dry hands with a paper towel
• D. Turn off the water faucet

Correct answer: A

Rationale: After wetting the hands and applying soap, the nurse should rub hands palm to palm. Rubbing hands palm to palm helps create friction and effectively clean the hands by spreading the soap and reaching all areas. Interlacing the fingers, drying hands with a paper towel, and turning off the water faucet should come after rubbing hands palm to palm in the handwashing process. Interlacing the fingers can be done to ensure the backs of the hands are cleaned, drying hands with a paper towel is the final step to ensure hands are dry, and turning off the water faucet helps save water.
