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 A
Explanation
Choice A reason : A severe, throbbing headache is a common and significant manifestation of autonomic dysreflexia. This condition is a potentially life-threatening medical emergency that can occur in individuals with spinal cord injuries, typically above the T6 level. The headache results from a sudden and severe increase in blood pressure due to an exaggerated response of the autonomic nervous system to a stimulus below the level of the injury.
Choice B reason: Hypotension, or low blood pressure, is not a manifestation of autonomic dysreflexia. In fact, the condition is characterized by hypertension, or high blood pressure, which is a critical sign that requires immediate attention to prevent complications such as stroke or seizure.
Choice C reason: Fever is not a direct manifestation of autonomic dysreflexia. While a fever may indicate an infection or other systemic issue, autonomic dysreflexia itself is specifically associated with a rapid onset of high blood pressure and other autonomic disturbances.
Choice D reason: Cyanosis of the head and neck, which refers to a bluish discoloration of the skin due to poor circulation or inadequate oxygenation of the blood, is not a typical manifestation of autonomic dysreflexia. The condition primarily causes hypertension and its associated symptoms, rather than issues with oxygenation.
Correct Answer is B
Explanation
Choice A reason: Glucose Dextrose Oral (GDO) is not typically used in the immediate management of anaphylactic shock. Anaphylaxis requires rapid treatment to address severe allergic reactions and GDO does not play a role in this emergency situation.
Choice B reason: Epinephrine (Adrenaline) is the first-line treatment for anaphylactic shock. It works quickly to improve breathing, stimulate the heart, raise a dropping blood pressure, reverse hives, and reduce swelling of the face, lips, and throat.
Choice C reason: Dexamethasone (Decadron) is a corticosteroid that may be used in the treatment of anaphylaxis to reduce inflammation. However, it is not the first medication administered due to its slower onset of action compared to epinephrine.
Choice D reason: 0.9% Normal Saline is used for intravenous fluid resuscitation in anaphylactic shock but is secondary to the administration of epinephrine. It helps to maintain blood pressure and is important in the overall management but not the first medication given.
