H₂ receptor antagonists (H₂RAs) do not directly address diarrhea, as their primary action is to reduce gastric acid secretion rather than influence bowel motility or consistency.

H₂RAs do not have a direct effect on constipation. Constipation is more related to bowel motility, which is not influenced by the mechanism of action of these drugs.

While the passage of flatus can indicate improved gastrointestinal function, it is not an expected therapeutic outcome of H₂RAs, as these medications target acid production rather than gas formation.

Assuming a narrow base of support would make the nurse less stable and increase the risk of both the nurse and the client falling. A wide base of support is essential for maintaining balance.

Leaning the client toward the wall may result in an uncontrolled fall, increasing the risk of injury to the client. It does not provide adequate support or control during the fall.

Holding the client’s arm alone does not provide sufficient support and can result in injury to the client, such as shoulder or arm strain, or to the nurse.

Algae, such as spirulina, contains compounds similar to Vitamin B12, but these are inactive analogs that are not effective for human absorption or use.

Sea vegetables, like nori and wakame, may contain trace amounts of Vitamin B12, but the levels are inconsistent and not reliable for meeting daily nutritional requirements.

Tempeh, a fermented soy product, does not naturally contain significant amounts of Vitamin B12 unless it has been fortified.

Placing the client in low Fowler's position increases the risk of aspiration. The client should be positioned in a high Fowler's position (at least 30-45 degrees) to promote safe feeding and reduce the risk of aspiration.

While warming the feeding solution to room temperature is acceptable, warming it to body temperature is unnecessary and could promote bacterial growth if not handled correctly.

Residual gastric contents should not be discarded unless specifically instructed by the provider. Instead, the amount should be measured to assess gastric emptying and tolerance to feedings.

Prolonged immobility does not directly decrease red blood cell (RBC) production. RBC production is primarily regulated by erythropoietin from the kidneys and oxygen demand, which may not be significantly altered by immobility alone.

Immobility typically reduces metabolic demand and insulin sensitivity rather than increasing insulin production. Insulin resistance is more commonly associated with prolonged immobility.

Immobility does not directly affect sodium excretion in a way that would cause it to decrease. Sodium balance is primarily regulated by the kidneys and other hormonal mechanisms unrelated to immobility.

A urine output of 2,200 mL in 24 hours is within normal limits for an adult (1,500–2,500 mL/day), and does not indicate impaired renal function.

A strong odor in the first-voided urine is not uncommon and may be due to the concentration of overnight urine. It is not necessarily indicative of renal impairment.

Cloudy urine after sitting in a urinal for 6 hours is likely due to the precipitation of urinary solutes and is not a reliable indicator of renal dysfunction.

Palpating pedal pulses assesses circulation, not strength. While important for overall assessment, it does not provide information about the client’s ability to bear weight or ambulate.

Asking the client to touch her finger to her nose assesses coordination rather than strength. This test is more relevant for evaluating neurological function.

Asking the client how strong she feels is subjective and does not provide an objective measure of physical strength.

Hematuria (blood in the urine) is not a common symptom of urinary incontinence. It is more often associated with urinary tract infections, kidney stones, or other urological conditions.

Urinary hesitancy is typically associated with conditions like benign prostatic hyperplasia (BPH) or urinary obstruction, not urinary incontinence.

Urinary urgency without frequency is more indicative of overactive bladder or urge incontinence, but it is not the most common finding in general urinary incontinence cases.

Weight-bearing exercise is important for bone health but does not directly trigger vitamin D synthesis. It helps utilize vitamin D in the process of bone remodeling.

Vitamin A depletion is unrelated to vitamin D synthesis. Both vitamins have distinct roles in the body and are metabolized independently.

Calcium is essential for bone health and works synergistically with vitamin D, but it does not trigger vitamin D formation. Vitamin D enhances calcium absorption in the gut.
