Adult Health 2 Exam 1
1. A client with a diagnosis of diabetes mellitus is experiencing symptoms of hypoglycemia. What is the nurse's priority intervention?
- A. Administer glucagon intramuscularly.
- B. Provide a complex carbohydrate snack.
- C. Administer 50% dextrose intravenously.
- D. Give 15 grams of a fast-acting carbohydrate.
Correct answer: D
Rationale: The correct answer is to give 15 grams of a fast-acting carbohydrate as the priority intervention in a client experiencing hypoglycemia. This helps quickly raise the blood glucose level. Administering glucagon intramuscularly (Choice A) is typically reserved for severe hypoglycemia where the client is unable to take oral carbohydrates. Providing a complex carbohydrate snack (Choice B) is not the priority in an acute hypoglycemic episode where immediate action is needed. Administering 50% dextrose intravenously (Choice C) is more invasive and usually reserved for cases where the client is unable to take anything by mouth.
2. A client is receiving a blood transfusion and reports chills and back pain. What is the nurse's priority action?
- A. Continue the transfusion at a slower rate
- B. Administer an antipyretic
- C. Stop the transfusion immediately
- D. Notify the healthcare provider
Correct answer: C
Rationale: When a client receiving a blood transfusion reports chills and back pain, it indicates a possible transfusion reaction. The nurse's priority action is to stop the transfusion immediately. Continuing the transfusion at a slower rate (Choice A) can exacerbate the reaction. Administering an antipyretic (Choice B) may help with fever but does not address the underlying issue of a transfusion reaction. Notifying the healthcare provider (Choice D) is important but should not delay the immediate action of stopping the transfusion to ensure the client's safety.
3. A client with a diagnosis of chronic heart failure is prescribed digoxin. What is the most important assessment before administering this medication?
- A. Check blood pressure
- B. Assess heart rate
- C. Monitor respiratory rate
- D. Measure oxygen saturation
Correct answer: B
Rationale: The correct answer is to assess the heart rate before administering digoxin. Digoxin can lead to bradycardia, making it crucial to evaluate the heart rate to prevent potential complications. Checking blood pressure (Choice A) is important but not as critical as assessing the heart rate in this context. Monitoring respiratory rate (Choice C) and measuring oxygen saturation (Choice D) are not the most crucial assessments before administering digoxin, as the primary concern with this medication is its impact on heart rate.
4. A client with chronic kidney disease is being evaluated for dialysis. Which laboratory value would be most concerning to the nurse?
- A. Hemoglobin 9.5 g/dL
- B. Potassium 6.2 mEq/L
- C. Creatinine 3.5 mg/dL
- D. BUN 50 mg/dL
Correct answer: B
Rationale: The correct answer is B: Potassium 6.2 mEq/L. In chronic kidney disease, the kidneys struggle to regulate potassium levels, leading to hyperkalemia. A potassium level of 6.2 mEq/L is dangerously high and can cause life-threatening cardiac arrhythmias. Hemoglobin of 9.5 g/dL may indicate anemia, which is common in chronic kidney disease but is not immediately life-threatening. Creatinine and BUN levels are markers of kidney function; although elevated levels indicate kidney impairment, they are not acutely life-threatening like severe hyperkalemia.
5. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?
- A. Filtration
- B. Diffusion
- C. Osmosis
- D. Active transport
Correct answer: C
Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.
