A nurse is preparing to obtain a guaiac smear sample from a client for fecal occult blood testing. Which of the following actions should the nurse plan to take?
Wear sterile gloves when collecting the sample.
Discard samples that contain urine.
Collect three samples from a single bowel movement.
Take the sample from the outer edge of formed stool.
The Correct Answer is B
Choice A reason: While wearing gloves is a standard precaution to prevent contamination and protect the nurse from potential pathogens, the gloves used for collecting a guaiac smear sample do not need to be sterile. Clean, non-sterile gloves are typically sufficient for this procedure.
Choice B reason: It is crucial to discard any samples that contain urine because urine can interfere with the results of the fecal occult blood test (FOBT). The presence of urine can cause false positives due to the peroxidase activity in urine, which can lead to unnecessary further testing.
Choice C reason: Collecting three samples from a single bowel movement is not recommended. Instead, it is advised to collect samples from three separate bowel movements to increase the likelihood of detecting intermittent bleeding, which is common in conditions like colorectal cancer.
Choice D reason: Taking the sample from the outer edge of formed stool is not the best practice. The sample should be taken from different areas of the stool to ensure a representative sample, as blood may not be uniformly distributed throughout the stool.

Correct Answer is D
Explanation
Choice A reason: Taking two tablets PO every 15 minutes is not the standard protocol for nitroglycerin administration for chest pain. This method could lead to an overdose and significant hypotension (low blood pressure), which can be dangerous.
Choice B reason: One tablet SL every 15 minutes, up to 5 times, is also not the standard protocol. While sublingual administration is correct, the frequency and the total number of doses are higher than recommended, which could result in adverse effects such as headache, dizziness, or a severe drop in blood pressure.
Choice C reason: One tablet PO every one hour, up to 5 times, is not a recommended method for acute chest pain relief from angina. Oral administration does not provide the rapid onset of action required for acute angina relief.
Choice D reason: One tablet SL every 5 minutes, up to 3 times, is the correct protocol for nitroglycerin administration when experiencing chest pain due to angina. If pain persists after the first dose, the patient can take a second dose after 5 minutes, and if needed, a third dose after another 5 minutes. If chest pain continues after three doses in 15 minutes, emergency medical help should be sought immediately.
Correct Answer is B
Explanation
Choice A reason: Hypotension, or low blood pressure, is not typically associated with thyroid storm. Thyroid storm is a life-threatening condition that often presents with hypertensive crisis due to the excessive amount of thyroid hormones accelerating the body's metabolism.
Choice B reason: Increased temperature is a hallmark sign of thyroid storm. Patients experiencing a thyroid storm can have a high fever, with temperatures ranging from 104°F to 106°F. This is due to the hypermetabolic state induced by excessive thyroid hormones, which increases the body's heat production.
Choice C reason: Lethargy is not a common symptom of thyroid storm. Instead, patients may experience agitation, irritability, and anxiety due to the overstimulation of the nervous system by excessive thyroid hormones. Lethargy might be observed in hypothyroidism, which is the opposite condition.
Choice D reason: A decreased heart rate is not characteristic of thyroid storm. On the contrary, tachycardia, or a rapid heart rate, is a common symptom. The heart rate can exceed 140 beats per minute as the body's demand for oxygen increases due to the hypermetabolic state.
