Question 1 of 5
A nurse is reviewing the laboratory values of a client who had a myocardial infarction 3 hr ago. The nurse should expect which of the following laboratory values to be elevated?
Correct Answer: C
Rationale: The correct answer is C: Troponin I. Troponin I is a specific marker for myocardial damage. After a myocardial infarction, the damaged heart muscle releases troponin I into the bloodstream, leading to elevated levels. This helps in diagnosing and monitoring the extent of myocardial damage.
A: Serum sodium levels are not typically affected by a myocardial infarction.
B: Serum glucose levels may be elevated due to stress response but are not specific to myocardial infarction.
D: White blood cell count may be elevated in response to inflammation caused by myocardial infarction, but it is not as specific as troponin I.
Question 2 of 5
A nurse is teaching a client who has been taking prednisone to treat asthma and has a new prescription to discontinue the medication. The nurse should explain to the client to reduce the dose gradually to prevent which of the following adverse effects?
Correct Answer: D
Rationale: The correct answer is D: Adrenocortical insufficiency. Gradually reducing prednisone dose is important as prednisone suppresses the body's natural production of cortisol. Abrupt discontinuation can lead to adrenal insufficiency due to the sudden decrease in cortisol levels. This can result in symptoms such as fatigue, weakness, weight loss, and hypotension. Osteoporosis (
A) is a long-term side effect of prednisone but not a concern with dose reduction. Hypoglycemia (
B) and Hyperkalemia (
C) are not typically associated with prednisone withdrawal.
Question 3 of 5
A nurse is assessing a client before a packed RBC transfusion. What data is most important to obtain?
Correct Answer: B
Rationale: The correct answer is B: Temperature. Before a packed RBC transfusion, it is crucial to assess the client's temperature as hyperthermia can indicate a possible transfusion reaction. Monitoring temperature helps in early detection and intervention. Blood pressure (
A) is important but not the most crucial in this context. Respiratory rate (
C) and oxygen saturation (
D) are relevant but may not indicate an immediate issue with the transfusion. Other choices are not provided.
Question 4 of 5
A nurse is caring for a client who reports a new onset of severe chest pain. Which of the following actions should the nurse take to determine if the client is experiencing a myocardial infarction?
Correct Answer: A
Rationale: The correct answer is A: Perform a 12-lead ECG. This is because an ECG is the most reliable and direct way to assess for myocardial infarction by identifying characteristic changes in the heart's electrical activity. Nitroglycerin (
B) is used to relieve chest pain but should not be administered before confirming the diagnosis. Placing the client in a prone position (
C) is not appropriate for assessing chest pain. Assessing blood pressure (
D) is important but not the initial priority when suspecting myocardial infarction.
Question 5 of 5
A staff nurse is teaching a client who has Addison's disease about the disease process. The client asks the nurse what causes Addison's disease. Which of the following responses should the nurse make?
Correct Answer: A
Rationale:
Correct Answer: A
Rationale:
1. Addison's disease is characterized by adrenal insufficiency.
2. Aldosterone is a hormone produced by the adrenal gland that helps regulate blood pressure and electrolyte balance.
3. Lack of aldosterone production in Addison's disease leads to electrolyte imbalances and low blood pressure.
4.
Therefore, the correct answer is A as the lack of aldosterone production by the adrenal gland is the primary cause of Addison's disease.
Summary of other choices:
B. Addison's disease is not caused by a viral infection, so this choice is incorrect.
C. Addison's disease is not caused by the overproduction of cortisol, as it is associated with cortisol deficiency.
D. The most common cause of Addison's disease is an autoimmune disorder where the body attacks the adrenal glands, leading to their dysfunction.
