A nurse is teaching a client how to obtain a specimen at home for a fecal occult blood test. Which of the following actions should the nurse instruct the client to take for 3 days prior to collecting the specimen?
- A. Avoid eating red meat.
- B. Increase fiber intake.
- C. Take an iron supplement.
- D. Drink grapefruit juice.
Correct Answer: A
Rationale: The correct answer is A: Avoid eating red meat. Red meat can cause false positives in fecal occult blood tests due to the presence of heme iron which can be mistaken for blood. Instructing the client to avoid red meat for 3 days prior to collecting the specimen helps to ensure the accuracy of the test results.
Summary:
B: Increasing fiber intake does not directly impact the accuracy of the fecal occult blood test.
C: Taking an iron supplement can interfere with the test results by increasing the amount of iron in the stool, leading to false positives.
D: Drinking grapefruit juice is not relevant to the accuracy of the fecal occult blood test.

A nurse is assessing a client who takes salmeterol to treat moderate asthma. Which of the following findings should indicate to the nurse that the medication has been effective?
- A. The client has decreased mucus production.
- B. The clients daily peak expiratory flow (PEF) measures 85% above personal best.
- C. The client has a respiratory rate of 24/min.
- D. The client reports no nighttime coughing.
Correct Answer: B
Rationale: The correct answer is B because an increase in the client's daily peak expiratory flow (PEF) by 85% above their personal best indicates improved lung function, which is a positive response to salmeterol. This demonstrates that the medication is effectively managing the asthma symptoms.
Choice A is incorrect because decreased mucus production is not a direct indicator of salmeterol's effectiveness in treating asthma. Choice C is incorrect as the respiratory rate alone does not provide specific information about the medication's effectiveness. Choice D is incorrect since the absence of nighttime coughing may be due to various factors and not solely because of salmeterol's effectiveness.
A nurse is assessing a client who has a history of type 2 diabetes mellitus. The nurse should identify which of the following findings as an indication of a microvascular complication?
- A. Peripheral neuropathy
- B. Hypertension
- C. Retinopathy
- D. Stroke
Correct Answer: C
Rationale: The correct answer is C: Retinopathy. In type 2 diabetes mellitus, microvascular complications involve damage to small blood vessels. Retinopathy specifically affects the blood vessels in the retina, leading to vision problems. Peripheral neuropathy (A) is a macrovascular complication affecting nerves. Hypertension (B) is a common comorbidity in diabetes but not a direct microvascular complication. Stroke (D) is a macrovascular complication involving larger blood vessels in the brain. Therefore, the presence of retinopathy is a clear indication of a microvascular complication in a client with type 2 diabetes mellitus.
A nurse in an emergency department is caring for a client who is confused, has a temperature of 40° C (104° F), a BP of 74/52 mm Hg, and a diagnosis of exertional heat stroke. Which of the following actions should the nurse take first?
- A. Administer oxygen using a high-concentration mask.
- B. Give the client cold fluids orally.
- C. Apply a heating pad to prevent shivering.
- D. Encourage the client to walk to promote circulation.
Correct Answer: A
Rationale: The correct answer is A: Administer oxygen using a high-concentration mask. In exertional heat stroke, the body's ability to regulate temperature is compromised, leading to confusion, high temperature, and low blood pressure. Oxygen therapy helps support oxygenation during heat stress. It takes priority to ensure adequate oxygenation and prevent hypoxia, which can worsen the client's condition. Choices B, C, and D are incorrect. Giving cold fluids orally can potentially induce shock in a hypotensive client. Applying a heating pad can lead to further increase in body temperature. Encouraging the client to walk can exacerbate heat stress and increase the risk of collapse.
A nurse is assessing a client who has a chest tube connected to a closed water-seal drainage system. Which of the following findings should the nurse report to the provider?
- A. Constant bubbling in the water seal chamber
- B. Intermittent bubbling in the suction chamber
- C. Clear drainage of 50 mL over 8 hours
- D. Mild pain at the insertion site
Correct Answer: A
Rationale: The correct answer is A: Constant bubbling in the water seal chamber. This finding indicates an air leak in the system, which can compromise the client's respiratory status. The continuous bubbling signifies that air is escaping through the chest tube rather than being properly drained. The nurse should report this to the provider immediately for further evaluation and intervention to prevent pneumothorax or other complications.
The other choices (B, C, D) are incorrect because intermittent bubbling in the suction chamber is expected as it indicates proper functioning of the system. Clear drainage of 50 mL over 8 hours is within normal limits and does not pose an immediate threat to the client. Mild pain at the insertion site is also a common finding after chest tube insertion and does not require urgent intervention unless it worsens or is accompanied by other concerning symptoms.
A nurse is caring for a male client who has a new prescription for cyclosporine following a kidney transplant. Which of the following findings should the nurse identify as an adverse effect of this therapy?
- A. BUN 24 mg/dL
- B. Blood glucose 95 mg/dL
- C. Platelets 250
- D. 000/mm³
- E. Hemoglobin 14 g/Dl
Correct Answer: A
Rationale: The correct answer is A: BUN 24 mg/dL. Cyclosporine, an immunosuppressant medication, can cause nephrotoxicity as an adverse effect. An elevated BUN level indicates impaired kidney function, which can be a consequence of cyclosporine therapy. Blood glucose level (choice B) and platelet count (choice C) are not typically affected by cyclosporine. Hemoglobin level (choice E) is not directly related to cyclosporine therapy. Therefore, the nurse should be vigilant for signs of nephrotoxicity by monitoring the client's BUN level.
