Nursing Elites

1. A client is receiving heparin therapy. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?

• A. PT
• B. aPTT
• C. INR
• D. Platelet count

Correct answer: B

Rationale: The corrected answer is B: aPTT. The activated partial thromboplastin time (aPTT) is the laboratory value used to monitor the effectiveness of heparin therapy. The aPTT should be maintained at 1.5 to 2 times the normal level to ensure therapeutic anticoagulation. Monitoring aPTT helps healthcare providers adjust heparin doses to achieve the desired anticoagulant effects and prevent complications such as bleeding or clotting. Choice A, PT (prothrombin time), is used to monitor warfarin therapy, not heparin. Choice C, INR (international normalized ratio), is also used to monitor warfarin therapy. Choice D, platelet count, is important for assessing the risk of bleeding, but it does not directly monitor the effectiveness of heparin therapy.

2. A client has a new prescription for Prednisone. Which of the following instructions should be included in the discharge teaching?

• A. Increase your intake of potassium-rich foods.
• B. Avoid consuming grapefruit juice.
• C. Take this medication with food.
• D. Decrease your intake of sodium-rich foods.

Correct answer: A

Rationale: The correct answer is A: "Increase your intake of potassium-rich foods." Prednisone is associated with potassium depletion, making it important for clients to increase their intake of potassium-rich foods to prevent potential imbalances. Foods such as bananas, oranges, and spinach are good sources of potassium. Choice B, "Avoid consuming grapefruit juice," is not directly related to Prednisone use. Choice C, "Take this medication with food," is a general instruction for many medications but not specific to Prednisone. Choice D, "Decrease your intake of sodium-rich foods," is not directly related to Prednisone's side effects.

3. A client in a long-term care facility has Hypothyroidism and a new prescription for Levothyroxine. Which of the following dosage schedules should the nurse expect for this client?

• A. The client will start at a high dose, and the dose will be tapered as needed.
• B. The client will remain on the initial dosage during the course of treatment.
• C. The client's dosage will be adjusted daily based on blood levels.
• D. The client will start on a low dose, which will be gradually increased.

Correct answer: D

Rationale: The nurse should expect that levothyroxine will be started at a low dose and gradually increased over several weeks. This cautious approach is crucial, especially in older adult clients, to prevent toxicity and ensure optimal therapeutic outcomes for managing hypothyroidism. Choice A is incorrect because starting at a high dose and tapering as needed is not the standard approach for levothyroxine. Choice B is incorrect because the initial dosage is typically adjusted to reach the optimal therapeutic dose. Choice C is incorrect as adjusting the dosage daily based on blood levels is not necessary for levothyroxine, as it has a long half-life and requires time to reach a steady state.

4. A client is starting a new prescription for levothyroxine. Which of the following instructions should the nurse include?

• A. Take the medication at bedtime.
• B. Take the medication with food.
• C. Take the medication first thing in the morning on an empty stomach.
• D. Take the medication with a full glass of milk.

Correct answer: C

Rationale: The correct instruction for taking levothyroxine is to take the medication first thing in the morning on an empty stomach. This timing is important for optimal absorption of the medication. Taking levothyroxine with food or at bedtime can interfere with its absorption. Milk and other foods, as well as certain medications, can reduce the effectiveness of levothyroxine by interfering with its absorption, so it should be taken separately from these items. Therefore, the correct choice is to take the medication first thing in the morning on an empty stomach.

5. A client with brain cancer and headaches is prescribed dexamethasone. What is the purpose of this adjuvant medication?

• A. To decrease inflammation and swelling
• B. To improve concentration
• C. To induce sedation
• D. To treat depression

Correct answer: A

Rationale: Dexamethasone, a glucocorticoid, is indicated for clients with brain cancer to decrease inflammation and swelling. It helps reduce cerebral edema and relieve pressure caused by the tumor, ultimately alleviating headaches. The purpose of prescribing dexamethasone in this case is not to improve concentration (choice B), induce sedation (choice C), or treat depression (choice D). Methylphenidate, a stimulant, is used for conditions like ADHD, not for brain cancer. Hydroxyzine, an antihistamine, is primarily used for anxiety and itching, not for brain cancer. Amitriptyline, a tricyclic antidepressant, is used for conditions like depression and neuropathic pain, not specifically for brain cancer-related headaches.
