A nurse in an emergency department is caring for a client who reports substernal chest pain and dyspnea. The client is vomiting and is diaphoretic. Which of the following laboratory tests are used to diagnose a myocardial infarction? (Select all that apply.)
- A. Troponin I, Troponin T, CPK, Myoglobin
- B. Plasma low-density lipoproteins
- C. White blood cell count
- D. Blood glucose level
Correct Answer: A
Rationale: The correct answer is A. Troponin I, Troponin T, CPK, and Myoglobin are all specific laboratory tests used to diagnose a myocardial infarction. Troponin I and T are cardiac biomarkers released into the bloodstream following myocardial cell injury. Creatine phosphokinase (CPK) is an enzyme found in high concentrations in the heart muscle, and elevated levels indicate myocardial damage. Myoglobin is a protein released from damaged muscle cells, including cardiac muscle. These tests provide crucial information to confirm the diagnosis of a myocardial infarction.
Plasma low-density lipoproteins are not specific for diagnosing a myocardial infarction. White blood cell count is not typically used for diagnosing a myocardial infarction, although it may be elevated in response to inflammation associated with heart damage. Blood glucose level is not specific for diagnosing a myocardial infarction and

A nurse is planning care for a client who is being treated with chemotherapy and radiation for metastatic breast cancer, and who has neutropenia. The nurse should include which of the following restrictions in the client's plan of care?
- A. Fresh flowers and potted plants in the room
- B. Use of public transportation
- C. Group activities
- D. Unrestricted visitors
Correct Answer: A
Rationale: The correct answer is A: Fresh flowers and potted plants in the room. Neutropenic clients are at high risk for infections due to low white blood cell count. Fresh flowers and plants can harbor bacteria and fungi that can potentially cause infections. Therefore, restricting fresh flowers and plants helps minimize the risk of infection. Choices B, C, and D are incorrect because they do not directly relate to the risk of infection in neutropenic clients. Using public transportation, engaging in group activities, or having visitors are generally safe as long as proper infection control measures are followed.
A nurse is teaching a client about the causes of osteoporosis. The nurse should include which of the following types of medication therapy as a risk factor for osteoporosis?
- A. Thyroid hormones
- B. Antihypertensives
- C. Steroids
- D. Insulin
Correct Answer: C
Rationale: The correct answer is C: Steroids. Steroids, specifically glucocorticoids, are known to increase the risk of osteoporosis by decreasing bone formation and increasing bone resorption. Long-term use of steroids can lead to bone loss, making individuals more susceptible to fractures. Thyroid hormones (A) do not directly cause osteoporosis. Antihypertensives (B) and insulin (D) are not associated with increased risk of osteoporosis.
A nurse is planning a teaching session about hysterosalpingography for a client who has a diagnosis of infertility. The nurse should include which of the following information in the teaching plan?
- A. The client might experience shoulder pain following the procedure.
- B. The client might experience nausea and vomiting after the procedure.
- C. The client will need to stay in bed for 24 hours post-procedure.
- D. The client should avoid drinking fluids before the procedure.
Correct Answer: A
Rationale: The correct answer is A: The client might experience shoulder pain following the procedure. This is because hysterosalpingography involves the injection of contrast dye into the uterus and fallopian tubes, which can cause referred pain to the shoulder due to irritation of the diaphragm. This information is crucial for the client to be aware of potential side effects.
The other choices are incorrect:
B: The client might experience nausea and vomiting after the procedure - This is not a common side effect of hysterosalpingography.
C: The client will need to stay in bed for 24 hours post-procedure - There is no requirement for prolonged bed rest after the procedure.
D: The client should avoid drinking fluids before the procedure - In fact, it is recommended to drink plenty of fluids before the procedure to help flush out the contrast dye.
A nurse is caring for a client who has heart failure and a new prescription for furosemide. For which of the following adverse effects should the nurse monitor?
- A. Hypokalemia
- B. Hyperkalemia
- C. Hypernatremia
- D. Hypertension
Correct Answer: A
Rationale: The correct answer is A: Hypokalemia. Furosemide is a loop diuretic that can cause potassium loss through increased urine output. This can lead to hypokalemia, which can be dangerous in a client with heart failure as it can worsen cardiac function and lead to arrhythmias. The nurse should monitor the client's potassium levels regularly to prevent this adverse effect.
Summary of other choices:
B: Hyperkalemia - Furosemide does not typically cause hyperkalemia.
C: Hypernatremia - Furosemide is a diuretic that can lead to sodium loss, not hypernatremia.
D: Hypertension - Furosemide is actually used to treat hypertension, so it is not an adverse effect of the medication in this scenario.
A nurse is reviewing laboratory values for a client who has systemic lupus erythematosus (SLE). Which of the following values should give the nurse the best indication of the client's renal function?
- A. Serum creatinine
- B. Serum potassium
- C. White blood cell count
- D. Hemoglobin level
Correct Answer: A
Rationale: The correct answer is A: Serum creatinine. Creatinine is a waste product produced by muscles and filtered out by the kidneys. In clients with SLE, renal involvement is common. Elevated serum creatinine levels indicate impaired renal function, as the kidneys are not effectively filtering out waste products. Monitoring serum creatinine levels helps assess renal function and detect kidney damage early.
Choices B, C, D, and E are incorrect as they do not directly reflect renal function. Serum potassium levels (B) are more indicative of electrolyte balance, white blood cell count (C) indicates immune response, and hemoglobin level (D) reflects oxygen-carrying capacity.
