Nursing Clinical Skills questions

Correct Answer: D

Rationale: The correct answer is D: 1 to 2 L/day. Normal urine output typically ranges from 1 to 2 liters per day, which is considered adequate for maintaining proper hydration and eliminating waste products. A: 80 to 125 mL/min is too low for daily output. B: 180 L/day is excessively high and unrealistic. C: 80 mL/min is also too low for daily urine output. Therefore, D is the most appropriate choice based on standard guidelines for urine excretion.

Correct Answer: D

Rationale: The correct answer is D. Auscultating the left arm for a bruit and palpating for a thrill post arteriovenous fistula implantation is crucial to assess the patency and functionality of the fistula. A bruit indicates turbulent blood flow, while a thrill signifies the presence of a strong pulse through the fistula. These assessments help identify any complications like stenosis or thrombosis. Drawing blood or taking blood pressures from the arm with the fistula can lead to inaccurate results or damage the fistula. Starting a new IV line in the left lower arm is unnecessary and not relevant to monitoring the arteriovenous fistula.

Correct Answer: A

Rationale: The correct answer is A: ADH deficiency. Diabetes insipidus is caused by a deficiency of antidiuretic hormone (ADH), leading to excessive urine production and thirst. ADH is responsible for regulating water reabsorption in the kidneys. When ADH levels are low or absent, the kidneys cannot concentrate urine effectively, resulting in excessive urine output. Explanation for why other choices are incorrect: B: ADH excess would not lead to diabetes insipidus, as it would result in increased water reabsorption and concentrated urine. C: ADH insensitivity refers to a condition where the body does not respond to ADH, but it does not cause diabetes insipidus. D: ADH replacement therapy is actually a treatment for diabetes insipidus, not a mechanism for its development.

Correct Answer: A

Rationale: The correct answer is A: Heredity. Nephrogenic diabetes insipidus can be inherited as a genetic condition. The mutation in genes responsible for regulating water balance in the kidneys can lead to this disorder. Other choices are incorrect: B: Medications like lithium can cause acquired nephrogenic diabetes insipidus, not its development. C: Meningitis is an inflammatory condition that does not directly relate to nephrogenic diabetes insipidus. D: Pituitary tumors are associated with central diabetes insipidus, not nephrogenic.

Correct Answer: A

Rationale: The correct answer is A: fluid retention of 1.5 liters. The weight gain from 5 kg to 99 kg indicates an increase of 94 kg. Since 1 kg of weight gain is approximately equal to 1 liter of fluid retention, the patient has retained 94 liters of fluid. Therefore, the correct choice is fluid retention of 1.5 liters. Choice B is incorrect because the weight gain indicates fluid retention, not loss. Choice C is incorrect as it mentions equal intake and output, which does not match the weight gain observed. Choice D is incorrect as it suggests fluid loss, which contradicts the weight gain.
