A nurse administering medications through a tube must remember which of the following?
Turn the patient to the right side once medications have been administered.
Leave patient in high-Fowler's position for 30 minutes after administering medication.
Flush the tube with 10-15 mL of water after each medication.
Hold the medication if 50 ml of residual is obtained.
The Correct Answer is B
Choice A rationale
Turning the patient to the right side immediately after medication administration via a tube is generally not recommended as it may promote rapid gastric emptying which can potentially lead to dumping syndrome or alter drug absorption by moving the medication out of the stomach too quickly.
Choice B rationale
Leaving the patient in a high-Fowler's position for 30 minutes after administering medications through a tube helps prevent aspiration by utilizing gravity to keep the medication in the stomach. This position also aids in proper digestion and absorption by maintaining gastrointestinal motility and reducing reflux.
Choice C rationale
Flushing the tube with 10-15 mL of water after each medication is generally insufficient to clear the tube effectively and prevent clogging, especially with viscous medications. A standard flush volume of 30-60 mL is typically recommended to ensure complete medication delivery and tube patency.
Choice D rationale
Holding medication if 50 mL of residual is obtained is not a universal standard. The acceptable residual volume varies based on institutional policy, patient condition, and the type of feeding. Often, a residual volume of 200-250 mL or more is the threshold for holding medications.

Correct Answer is C
Explanation
Choice A rationale
Pain sensation behind the eyes, particularly during palpation of the frontal or ethmoid sinuses, suggests inflammation or infection within these sinuses. Under normal conditions, healthy paranasal sinuses are air-filled cavities and should not elicit pain upon palpation.
Choice B rationale
Pain during palpation of any sinus area is indicative of sinusitis or inflammation. The presence of pain signifies pressure buildup, mucosal edema, or infection within the sinus cavities. Normal findings would not involve pain, but rather a sensation of mild pressure.
Choice C rationale
Normal findings during sinus palpation should elicit a sensation of pressure but no pain or tenderness. This indicates that the sinuses are air-filled, patent, and free from inflammation or congestion. The pressure is a result of the gentle digital compression over the bony structures.
Choice D rationale
Tingling along the nose and eyes is not a typical sensation associated with normal sinus palpation. This sensation might suggest neurological irritation, such as nerve compression or neuropathy, rather than a direct physiological response from the paranasal sinuses themselves.
Correct Answer is C
Explanation
Choice A rationale
Lymphadenopathy refers to enlarged lymph nodes, which are palpable structures of the immune system. Bruits are vascular sounds, specifically turbulent blood flow, and are entirely unrelated to the presence or size of lymph nodes. Lymphadenopathy indicates an immune response or lymphatic system issue, whereas bruits indicate arterial pathology.
Choice B rationale
Hypermetabolic states, such as hyperthyroidism, can increase cardiac output and blood flow velocity, potentially leading to flow murmurs in the heart. However, they do not directly cause bruits in the carotid arteries. Carotid bruits are typically indicative of localized arterial narrowing or disease, not a systemic increase in metabolism.
Choice C rationale
Bruits are audible vascular sounds, often described as a "whooshing" or "swishing" sound, that result from turbulent blood flow through a narrowed or partially occluded artery. In the carotid arteries, a bruit strongly suggests atherosclerotic plaque formation, which reduces the arterial lumen and disrupts the smooth, laminar flow of blood, creating turbulence.
Choice D rationale
Bruits are arterial sounds, reflecting turbulence within arteries. Venous disease primarily involves veins, and while some venous conditions like arteriovenous fistulas can produce continuous murmurs, typical bruits heard over carotid arteries are characteristic of arterial narrowing and compromise, not venous pathology. Venous hums can occur but are distinctly different from arterial bruits.
