1. The nurse is caring for a patient who develops marked edema and a low urine output as a result of heart failure. Which medication will the nurse expect the provider to order for this patient?
- A. Digoxin (Lanoxin)
- B. Furosemide (Lasix)
- C. Hydrochlorothiazide (HydroDIURIL)
- D. Spironolactone (Aldactone)
Correct answer: B
Rationale: In heart failure with marked edema and low urine output, the nurse can expect the provider to order Furosemide (Lasix). Furosemide is a loop diuretic that acts quickly to remove excess fluid from the body, making it an appropriate choice for this patient's condition. Digoxin is used to improve heart function but does not directly address fluid overload. Hydrochlorothiazide is a thiazide diuretic that is not as potent as Furosemide in managing acute fluid retention. Spironolactone is a potassium-sparing diuretic that is typically used in heart failure for its aldosterone-blocking effects and not for immediate fluid removal.
2. The client has had a femoral-popliteal bypass surgery 6 hours ago. Which assessment provides the most accurate information about the client's postoperative status?
- A. Radial pulse.
- B. Femoral pulse.
- C. Apical pulse.
- D. Dorsalis pedis pulse.
Correct answer: D
Rationale: Assessing the dorsalis pedis pulse is crucial after a femoral-popliteal bypass surgery to determine adequate circulation distal to the surgical site. A strong dorsalis pedis pulse indicates sufficient blood flow to the foot, which is essential for monitoring postoperative status. The radial pulse (A) is not the most relevant assessment as it does not provide direct information on circulation in the lower extremities. The femoral pulse (B) may not accurately reflect circulation distal to the surgical site. The apical pulse (C) is used primarily to assess the heartbeat and cardiac function, not circulation in the lower extremities.
3. In a patient with type 1 diabetes, which of the following is a sign of diabetic ketoacidosis (DKA)?
- A. Polyuria
- B. Bradycardia
- C. Dry skin
- D. Tachycardia
Correct answer: D
Rationale: Tachycardia is a sign of diabetic ketoacidosis (DKA) in a patient with type 1 diabetes. In DKA, the body responds to hyperglycemia and dehydration by increasing heart rate. Polyuria (increased urination) is a symptom of diabetes but not specific to DKA. Bradycardia (slow heart rate) and dry skin are not typical signs of DKA; instead, tachycardia and other signs of volume depletion are more common.
4. Which of the following symptoms would a healthcare provider expect to find in a patient with hyperkalemia?
- A. Muscle cramps.
- B. Hypertension.
- C. Bradycardia.
- D. Tachycardia.
Correct answer: D
Rationale: Tachycardia is the correct symptom to expect in a patient with hyperkalemia. Hyperkalemia, or high potassium levels in the blood, can affect the electrical activity of the heart. Increased potassium levels can lead to changes in the heart's rhythm, potentially causing tachycardia (rapid heart rate) or other cardiac arrhythmias. Muscle cramps (choice A) are not typically associated with hyperkalemia. Hypertension (choice B) is not a common symptom of hyperkalemia; in fact, high potassium levels can sometimes cause low blood pressure. Bradycardia (choice C), or a slow heart rate, is usually not a primary symptom of hyperkalemia; instead, hyperkalemia tends to be associated with faster heart rates or arrhythmias.
5. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?
- A. To broaden the antibacterial spectrum.
- B. To decrease bacterial resistance.
- C. To improve the taste.
- D. To minimize toxic effects.
Correct answer: B
Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.
