Pharmacology and the Nursing Process 10th Edition Test Bank

Correct Answer: A

Rationale: The correct answer is A: Deficient fluid volume related to osmotic diuresis. With a serum glucose level of 618mg/dl, the client is likely experiencing diabetic ketoacidosis, leading to excessive urination (osmotic diuresis) and dehydration. The priority is to address fluid volume deficit to prevent hypovolemic shock. The other options are not the priority because: B: Decreased cardiac output is a result of the increased heart rate, not the primary issue. C: Imbalanced nutrition is important but not as urgent as fluid volume deficit. D: Ineffective thermoregulation is a concern but not the priority in this scenario.

Correct Answer: D

Rationale: The correct answer is D. In Addison's disease, the adrenal glands do not produce enough cortisol and aldosterone. This leads to sodium and potassium imbalances. Low aldosterone causes sodium loss and potassium retention, resulting in sodium and potassium abnormalities. The other choices, A, B, and C, do not directly relate to Addison's disease. Calcium and phosphorus abnormalities are not typically associated with Addison's disease. Sodium and chloride, and chloride and magnesium imbalances are not primary concerns in Addison's disease. Therefore, staying alert for signs and symptoms of sodium and potassium abnormalities is crucial in managing and monitoring a client with Addison's disease.

Correct Answer: D

Rationale: The correct answer is D, "Eliminate background noise." This technique is essential for older patients as they may have age-related hearing impairments. By reducing background noise, the patient can better focus on the information being conveyed. Sitting in bright sunlight (A) may cause glare and make it difficult to read or see clearly. Speaking in a high tone (B) may be perceived as aggressive or patronizing. Using small, white-on-black printed materials (C) may be challenging for older patients with visual impairments. Thus, eliminating background noise is the most effective technique to improve learning in preoperative older patients.

Correct Answer: D

Rationale: Pulmonary edema causes an increase in pressure in the pulmonary circulation, leading to an alteration in afterload due to increased resistance. It also causes fluid accumulation in the pulmonary vessels, affecting preload. Additionally, the heart may compensate by increasing contractility. Therefore, all of the above choices are altered in pulmonary edema. The incorrect choices are A, B, and C individually as they only represent one aspect of the alterations seen in pulmonary edema, while the correct answer D encompasses all three factors affected in this condition.

Correct Answer: C

Rationale: Rationale: - A: Diuretics are not necessary before the test and may affect test results. - B: Dehydration is not recommended before the test as it can impact cardiac function. - C: Medication to relieve cough is necessary to reduce any potential interference with the scan. - D: Administering analgesics is not required for the test and may not be relevant to the client's condition.
