Fundamentals of Nursing HESI

Correct Answer: D

Rationale: When a nurse observes peristomal skin irritation while changing a client's colostomy pouch, it is crucial to ensure that the pouch is slightly larger (0.32 cm or 1/8 inch) than the stoma. This extra space helps prevent the pouch from rubbing against the stoma and causing further irritation. Option A is correct because colostomy pouches should be changed based on individual needs, not necessarily every 24 hours. Option B is incorrect because applying the pouch only when the skin barrier is completely dry ensures better adhesion. Option C is incorrect as patting the peristomal skin dry after cleaning is more gentle and less likely to cause irritation compared to rubbing.

Correct Answer: A

Rationale: Calf swelling is a common sign of thrombophlebitis, which is inflammation of a vein due to a blood clot. Prolonged immobility can predispose individuals to thrombophlebitis. Calf swelling occurs due to the obstruction of blood flow, causing localized edema. This condition can lead to serious complications like pulmonary embolism if not promptly addressed. Elevated blood pressure, decreased urine output, and a generalized rash are not typically associated with thrombophlebitis. Elevated blood pressure may be linked to other conditions like hypertension, decreased urine output to kidney dysfunction, and a generalized rash to allergic reactions or skin conditions. Therefore, in a client on bed rest, calf swelling should raise suspicion of thrombophlebitis and prompt further evaluation and intervention.

Correct Answer: A

Rationale: When a client with an indwelling catheter reports a need to urinate, the nurse's initial action should be to check the catheter for patency. This is crucial to ensure that the catheter is not blocked, twisted, or kinked, which could lead to urinary retention. Reassuring the client without assessing the catheter could delay necessary interventions. Re-catheterizing the bladder with a larger-gauge catheter should not be the first step unless catheter patency is confirmed as an issue. Collecting a urine specimen for analysis is important but not the immediate priority when the client reports a need to urinate.

Correct Answer: A

Rationale: The nurse would most likely suspect fungi as the cause of thickened and separated toenails. Fungal infections can lead to changes in the nail structure, causing them to thicken and separate from the nail bed. Friction, nail polish, and nail polish remover are less likely to cause these specific nail changes. Friction typically leads to calluses or blisters, while nail polish and nail polish remover do not commonly result in thickened and separated toenails.

Correct Answer: C

Rationale: Dehydration is the primary factor to consider in this scenario. Dehydration leads to decreased skin turgor and tenting, where the skin does not return to its normal position when pinched. While thin, parchment-like skin, loss of adipose tissue, and diminished skin elasticity can contribute to skin changes, they are not the primary cause of the significant tenting observed.
