A nurse is caring for a client who has a new prescription for warfarin. Which of the following laboratory tests should the nurse use to monitor the client's therapeutic response to the medication?
- A. INR
- B. aPTT
- C. Platelet count
- D. Hemoglobin A1C
Correct Answer: A
Rationale: The correct answer is A: INR. The INR (International Normalized Ratio) is the laboratory test used to monitor the therapeutic response of warfarin. It helps ensure that the client's clotting time is within the desired range to prevent complications such as excessive bleeding or clotting. Choice B, aPTT (Activated Partial Thromboplastin Time), is not typically used to monitor warfarin therapy but rather for assessing heparin therapy. Choice C, Platelet count, assesses the number of platelets in the blood and is not specifically used to monitor warfarin therapy. Choice D, Hemoglobin A1C, is a test used to monitor long-term blood sugar control in diabetic patients and is not relevant to monitoring warfarin therapy.

A healthcare provider is reviewing the medical records of a client with a prescription for combination oral contraceptives. Which of the following conditions is a contraindication?
- A. Hyperthyroidism
- B. Thrombophlebitis
- C. Diverticulosis
- D. Hypocalcemia
Correct Answer: B
Rationale: Thrombophlebitis is a contraindication to combination oral contraceptives due to the increased risk of thromboembolic events. Hyperthyroidism, diverticulosis, and hypocalcemia are not contraindications to combination oral contraceptives. Hyperthyroidism may affect thyroid hormone levels but does not directly contraindicate oral contraceptives. Diverticulosis is a condition related to the digestive system and does not impact the use of oral contraceptives. Hypocalcemia, a low calcium level in the blood, is not a contraindication for oral contraceptives.
A nurse is reviewing the plan of care for a client who is in the manic phase of bipolar disorder. Which of the following interventions should the nurse expect to include?
- A. Encourage group activities to promote socialization.
- B. Encourage the client to take frequent naps throughout the day.
- C. Provide the client with frequent high-calorie snacks.
- D. Promote physical activity during mealtimes to stimulate appetite.
Correct Answer: C
Rationale: Providing high-calorie snacks is essential when caring for a client in the manic phase of bipolar disorder because they often have increased energy expenditure and may not eat adequately due to their heightened activity levels. Encouraging group activities (Choice A) may overwhelm the client further during this phase. Encouraging frequent naps (Choice B) contradicts the need to manage increased energy levels. Promoting physical activity during mealtimes (Choice D) may not be appropriate as it can distract the client from eating, which is crucial in meeting their nutritional needs.
A nurse is assessing a client who is immediately postoperative following a subtotal thyroidectomy. Which of the following should the nurse expect to administer?
- A. Calcium gluconate
- B. Sodium bicarbonate
- C. Potassium chloride
- D. Sodium phosphate
Correct Answer: A
Rationale: Calcium gluconate is the correct answer because it is administered to treat hypocalcemia, a common complication post-thyroidectomy. After a thyroidectomy, there is a risk of damaging the parathyroid glands, which can lead to a decrease in calcium levels. Administering calcium gluconate helps to raise calcium levels. Sodium bicarbonate (Choice B) is not typically indicated for immediate postoperative care following a subtotal thyroidectomy. Potassium chloride (Choice C) is not directly related to the common complications of this specific surgery. Sodium phosphate (Choice D) is not typically used to address immediate postoperative issues post-thyroidectomy.
A nurse is preparing to administer an IM injection to a client. Which of the following actions should the nurse take?
- A. Massage the injection site after administering the medication.
- B. Insert the needle at a 45° angle.
- C. Use a Z-track technique to administer the injection.
- D. Aspirate for blood before injecting the medication.
Correct Answer: C
Rationale: The correct answer is C: 'Use a Z-track technique to administer the injection.' When administering IM injections, using a Z-track technique helps prevent medication from leaking into subcutaneous tissues. This technique involves pulling the skin laterally, injecting the medication deeply into the muscle, and then releasing the skin. Choice A is incorrect because massaging the injection site after administering the medication can lead to increased blood flow and potential leakage of the medication. Choice B is incorrect as the needle should typically be inserted at a 90° angle for IM injections to ensure proper delivery into the muscle. Choice D is incorrect as aspirating for blood before injecting the medication is not routinely recommended for IM injections.
A client with a new diagnosis of peptic ulcer disease is receiving teaching from a nurse. Which of the following statements by the client indicates an understanding of the teaching?
- A. I will avoid taking ibuprofen for my pain.
- B. I will avoid eating spicy foods.
- C. I will limit my intake of dairy products.
- D. I will take my antacids 30 minutes before meals.
Correct Answer: B
Rationale: The correct answer is B. Clients with peptic ulcer disease should avoid spicy foods as they can exacerbate symptoms and delay healing. Ibuprofen can worsen peptic ulcers by irritating the stomach lining, so it should be avoided. While limiting dairy products may be beneficial for some individuals with lactose intolerance, it is not a specific recommendation for peptic ulcer disease. Taking antacids before meals can help neutralize stomach acid; however, the timing may vary depending on the type of antacid, so there is no universal rule of taking antacids 30 minutes before meals. Choice A is incorrect because the client should avoid taking ibuprofen due to its potential to worsen peptic ulcers. Choice C is incorrect as there is no direct correlation between dairy product intake and peptic ulcer disease. Choice D is incorrect because the timing of antacid administration can vary and should be guided by specific recommendations.
