The physician orders furosemide (Lasix) 40 mg IV STAT for an acutely fluid-overloaded patient. Why was the IV route likely chosen?
- A. Furosemide can be administered only by the IV route.
- B. IV is the route of choice for rapid administration.
- C. IV dosing is more accurate.
- D. IV furosemide has a fewer side effects than oral.
Correct Answer: B
Rationale: The correct answer is B: IV is the route of choice for rapid administration. IV route allows for quick onset of action, crucial in acutely fluid-overloaded patients needing immediate diuresis. Option A is incorrect as furosemide can be given orally too. Option C is less relevant in this urgent situation where speed is key. Option D is also incorrect as the side effects are not determined by route of administration.

The nurse would evaluate that the patient understands what triggers allergic rhinitis by which of the following patient responses?
- A. “Injected medications.”
- B. “Ingested food and medications.”
- C. “Topical creams and ointments.”
- D. “Airborne pollens and molds.”
Correct Answer: D
Rationale: The correct answer is D because airborne pollens and molds are common triggers for allergic rhinitis. Understanding these triggers helps in avoiding exposure and managing symptoms. Choices A, B, and C are incorrect as they do not specifically relate to allergic rhinitis triggers, focusing instead on other forms of medication or topical applications. By understanding airborne triggers, the patient can take appropriate preventive measures.
The nurse has entered a client’s room to find the client diaphoretic (sweat-covered) and shivering, inferring that the client has a fever. How should the nurse best follow up this cue and inference?
- A. Measure the client’s oral temperature.
- B. Ask a colleague for assistance.
- C. Give the client a clean gown and warm blankets.
- D. Obtain an order for blood cultures.
Correct Answer: A
Rationale: Step 1: Assess the client's vital signs to confirm presence of fever.
Step 2: Measure client's oral temperature to obtain accurate reading.
Step 3: Document temperature and report findings to healthcare provider.
Step 4: Initiate appropriate interventions based on temperature reading.
Step 5: Reassess client's condition to evaluate effectiveness of interventions.
Summary: Option A is correct as it directly addresses the cue of fever by confirming the temperature. Options B, C, and D are incorrect as they do not directly address the need to assess the client's temperature for accurate evaluation and intervention.
The nurse should include which of the following in preprocedure teaching for a patient scheduled for carotid angiography?
- A. "You will be put to sleep before the needle Is inserted."
- B. "The test will take several hours."
- C. "You may fee! a burning sensation when the dye is injected."
- D. "There will be no complications."
Correct Answer: C
Rationale: The correct answer is C: "You may feel a burning sensation when the dye is injected." This is important preprocedure teaching for carotid angiography because it prepares the patient for a common sensation during the procedure, helping to manage their expectations and reduce anxiety. This information is crucial for informed consent.
Choice A is incorrect because carotid angiography is usually done under local anesthesia, not general anesthesia. Choice B is incorrect as carotid angiography typically takes about 1-2 hours, not several hours. Choice D is incorrect because all medical procedures, including carotid angiography, carry potential risks and complications, which should be discussed with the patient.
For the first 72 hours thyroidectomy surgery, the nurse would assess the client for Chvostek’s sign and Trousseau’s sign because they indicate which of the following?
- A. Hypocalcamia
- B. hypokalemia
- C. Hypercalcemia
- D. Hyperkalemia
Correct Answer: A
Rationale: The correct answer is A: Hypocalcemia. Chvostek's sign and Trousseau's sign are both indicators of hypocalcemia, which is a common complication following thyroidectomy surgery due to potential damage to the parathyroid glands. Chvostek's sign is elicited by tapping the facial nerve and observing facial muscle twitching, while Trousseau's sign involves carpal spasm induced by inflating a blood pressure cuff above systolic pressure. Both signs are sensitive indicators of hypocalcemia due to their association with neuromuscular irritability. Hypercalcemia (option C) and hyperkalemia (option D) are not typically associated with thyroidectomy surgery and would not present with these specific signs. Hypokalemia (option B) is not related to Chvostek's sign and Trousseau's sign.
For a client with low blood volume, what are the implications of decreasing blood pressure and a rapid heart rate?
- A. Compression of blood vessels due to blood loss
- B. Increase in the circulating blood volume
- C. Inadequate renal perfusion
- D. Hypovolemia and shock
Correct Answer: D
Rationale: The correct answer is D: Hypovolemia and shock.
Rationale:
1. Low blood volume leads to decreased blood pressure and rapid heart rate as compensatory mechanisms.
2. These signs indicate inadequate perfusion due to reduced blood volume.
3. Hypovolemia can progress to shock if not addressed promptly.
Summary:
A: Compression of blood vessels is not directly related to low blood volume.
B: Increasing circulating blood volume would not occur in a client with low blood volume.
C: Inadequate renal perfusion is a consequence of hypovolemia, not an implication of decreasing blood pressure and rapid heart rate.
