Nursing Elites

1. The nurse is assisting the mother of a child with phenylketonuria (PKU) to select foods that are in keeping with the child's dietary restrictions. Which foods are contraindicated for this child?

• A. Wheat products
• B. Foods sweetened with aspartame
• C. High-fat foods
• D. High-calorie foods

Correct answer: B

Rationale: The correct answer is B: Foods sweetened with aspartame. Aspartame should not be consumed by a child with PKU because it is converted to phenylalanine in the body, which can be harmful to individuals with PKU. Choice A (Wheat products) is not specifically contraindicated for PKU. Choice C (High-fat foods) and Choice D (High-calorie foods) are not typically restricted in PKU diets unless they contain high levels of phenylalanine.

2. The healthcare provider prescribes ceftazidime (Fortaz) 35 mg every 8 hours IM for an infant. The 500 mg vial is labeled with the instruction to add 5.3 ml diluent to provide a concentration of 100 mg/ml. How many ml should the nurse administer for each dose?

• A. 0.35 ml
• B. 0.40 ml
• C. 0.50 ml
• D. 0.45 ml

Correct answer: B

Rationale: To calculate the volume to be administered for 35 mg of ceftazidime, divide the prescribed dose by the concentration: 35 mg / 100 mg/ml = 0.35 ml. Rounding off, the nurse should administer 0.4 ml for each dose. Choice A is incorrect as it doesn't consider rounding off. Choice C is incorrect because it's not the correct calculation. Choice D is incorrect as it doesn't reflect the accurate volume needed.

3. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which intervention should the nurse implement first?

• A. Administer intravenous fluids.
• B. Monitor the client's urine output.
• C. Obtain a blood glucose level.
• D. Administer 50% dextrose IV push.

Correct answer: D

Rationale: The correct answer is to administer 50% dextrose IV push first. In hyperglycemic hyperosmolar syndrome, the main goal is to rapidly reduce blood glucose levels to prevent further complications. Administering dextrose intravenously can help reverse the effects of high blood glucose levels quickly. Administering intravenous fluids, monitoring urine output, and obtaining a blood glucose level are important interventions but are not the first priority in treating HHS. Administering 50% dextrose IV push takes precedence as it directly addresses the elevated blood glucose levels.

4. Sublingual nitroglycerin is administered to a male client with unstable angina who complains of crushing chest pain. Five minutes later, the client becomes nauseated, and his blood pressure drops to 60/40 mm Hg. Which intervention should the nurse implement?

• A. Administer a second dose of nitroglycerin.
• B. Infuse a rapid IV normal saline bolus.
• C. Begin external chest compressions.
• D. Give a PRN antiemetic medication.

Correct answer: B

Rationale: The correct intervention in this situation is to infuse a rapid IV normal saline bolus. The client's drop in blood pressure to 60/40 mm Hg after nitroglycerin administration indicates hypotension, which may suggest a right ventricular infarction. Normal saline bolus helps to increase intravascular volume, improve cardiac output, and support blood pressure. Administering a second dose of nitroglycerin would further decrease blood pressure. External chest compressions are not indicated as the client's heart is still beating, and there is no indication for CPR. Giving an antiemetic medication is not the priority in this situation where hypotension is the main concern.

5. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value requires immediate intervention?

• A. Serum glucose of 600 mg/dL
• B. Serum osmolarity of 320 mOsm/kg
• C. Serum sodium of 130 mEq/L
• D. Serum potassium of 5.0 mEq/L

Correct answer: B

Rationale: A serum osmolarity of 320 mOsm/kg is concerning in a client with HHS because it indicates severe dehydration and hyperosmolarity, which requires immediate intervention. In HHS, the elevated serum osmolarity leads to neurological symptoms and can result in serious complications if not addressed promptly. While a high serum glucose level (choice A) is typical in HHS, the osmolarity is a more direct indicator of dehydration and severity. Serum sodium (choice C) and potassium levels (choice D) are important but do not pose an immediate threat to the client's condition compared to the severe hyperosmolarity indicated by a high serum osmolarity level.
