Nursing Elites

1. The nurse is evaluating the laboratory reports of a client with hypothyroidism. The nurse would expect which of the following laboratory values?

• A. Increased TSH
• B. Increased thyroxine (T4)
• C. Decreased TSH
• D. Decreased T3

Correct answer: A

Rationale: The correct answer is A: Increased TSH. In hypothyroidism, the thyroid gland is underactive, leading to low levels of thyroid hormones. As a compensatory mechanism, the pituitary gland releases more thyroid-stimulating hormone (TSH) to try to stimulate the thyroid gland to produce more hormones. Therefore, increased TSH levels are expected in hypothyroidism. Choice B is incorrect because in hypothyroidism, thyroxine (T4) levels are usually decreased, not increased. Choice C is incorrect as hypothyroidism is characterized by increased TSH levels, not decreased. Choice D is also incorrect because in hypothyroidism, T3 levels may be decreased, but TSH is a more sensitive indicator for diagnosis.

2. A client is receiving lactulose for signs of hepatic encephalopathy. To evaluate the therapeutic response, which assessment should the nurse obtain?

• A. Percussion of the abdomen.
• B. Blood glucose level.
• C. Serum electrolytes.
• D. Level of consciousness.

Correct answer: D

Rationale: The correct answer is D: Level of consciousness. Lactulose is used to reduce ammonia levels in hepatic encephalopathy, which can affect brain function. Therefore, monitoring the client's level of consciousness is crucial to evaluate the therapeutic response. Changes in consciousness can indicate the effectiveness of lactulose in reducing ammonia levels. Choices A, B, and C are incorrect because while they are important assessments in various conditions, they are not specifically related to evaluating the therapeutic response of lactulose in hepatic encephalopathy.

3. To prevent unnecessary hypoxia during suctioning of a tracheostomy, what must the nurse do?

• A. Apply suction for no more than 10 seconds
• B. Maintain sterile technique
• C. Lubricate 3 to 4 inches of the catheter tip
• D. Withdraw catheter in a circular motion

Correct answer: A

Rationale: The correct answer is to apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia, so it is essential to limit the suctioning time. Maintaining sterile technique (choice B) is important to prevent infections but is not directly related to preventing hypoxia during suctioning. Lubricating the catheter tip (choice C) helps with insertion but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not help prevent hypoxia.

4. A client receiving IV heparin reports abdominal pain and tarry stools. What is the nurse's priority action?

• A. Prepare to administer protamine sulfate.
• B. Continue the heparin infusion and notify the healthcare provider.
• C. Monitor the client's vital signs and assess abdominal pain.
• D. Administer a PRN dose of morphine sulfate.

Correct answer: A

Rationale: The correct answer is to prepare to administer protamine sulfate. Abdominal pain and tarry stools are indicative of gastrointestinal bleeding, a serious side effect of heparin therapy. Protamine sulfate is the antidote for heparin and is used to reverse its effects in cases of bleeding. Continuing the heparin infusion (Choice B) is not appropriate when the client is experiencing signs of bleeding. Monitoring vital signs and assessing abdominal pain (Choice C) is important but not the priority when immediate action is required to address potential bleeding. Administering morphine sulfate (Choice D) is not the priority in this situation; addressing the underlying cause of bleeding takes precedence.

5. While changing a client's chest tube dressing, the nurse notes a cracking sensation when gentle pressure is applied to the skin at the insertion site. What should the nurse do next?

• A. Apply a pressure dressing at the chest tube site.
• B. Administer an oral antihistamine per PRN order.
• C. Assess the client for allergies to topical cleaning agents.
• D. Measure the area of crackling and swelling.

Correct answer: D

Rationale: Measuring the area of crackling and swelling is essential in monitoring the progression of subcutaneous emphysema, which can result from air leaking into the tissues around the chest tube insertion site. This technique helps evaluate the extent of the issue and guides further interventions. Applying a pressure dressing (choice A) might exacerbate the condition by trapping more air. Administering an oral antihistamine (choice B) is not indicated for subcutaneous emphysema. Assessing for allergies to topical cleaning agents (choice C) is not the priority in this situation compared to evaluating and managing the subcutaneous emphysema.
