Correct Answer: C

Rationale: Applying lotion to the feet, avoiding between toes, is correct; over-the-counter treatments and soaking are not recommended.

Correct Answer: A

Rationale: Erythema on pressure points indicates potential skin breakdown due to prolonged immobility. It requires immediate intervention to prevent pressure ulcers. Lower-extremity pulse strength of 2+ is a normal finding, indicating adequate peripheral perfusion. Fluid intake of 3,000 mL per day is within the normal range and promotes hydration. A bowel movement every other day is a reasonable frequency for some individuals and does not necessarily indicate a need for immediate intervention in this scenario.

Correct Answer: B

Rationale: When a nurse asks a client to identify a number traced on the palm of the hand with their eyes closed, it assesses the client's ability to perceive touch sensations. This test specifically evaluates the tactile discrimination of the client. The other options do not test the client's ability to identify sensations accurately with eyes closed. Option A tests auditory perception, option C tests vibratory sense, and option D tests object recognition but not tactile discrimination, making them incorrect choices.

Correct Answer: D

Rationale: Chest pain in a client with hypertension is the most concerning symptom as it may indicate a myocardial infarction or other serious cardiac event related to hypertension. Immediate intervention is required to address potential life-threatening conditions. Headache, blurred vision, and dizziness are common symptoms associated with hypertension but are not typically indicative of an acute cardiac event requiring urgent attention.

Correct Answer: C

Rationale: The correct answer is C, 'Decreased potassium.' Clients with bulimia often have decreased potassium levels due to frequent vomiting, which causes a loss of this essential electrolyte. This loss can lead to various complications such as cardiac arrhythmias. Option A, 'Increased serum glucose,' is not typically associated with bulimia. Option B, 'Decreased albumin,' is more related to malnutrition or liver disease rather than bulimia. Option D, 'Increased sodium retention,' is not a common finding in clients with bulimia; instead, they may experience electrolyte imbalances like hyponatremia due to purging behaviors.
