Nursing Elites

1. . A nurse assesses a client with diabetes mellitus who is admitted with an acid-base imbalance. The clients arterial blood gas values are pH 7.36, PaO2 98 mm Hg, PaCO2 33 mm Hg, and HCO3 18 mEq/L. Which manifestation should the nurse identify as an exam

• A. Increased rate and depth of respirations
• B. ncreased urinary output
• C. Increased thirst and hunger
• D. ncreased release of acids from the kidneys

Correct answer: A

Rationale:

2. Retention of electrolytes (especially sodium) in the interstitial fluid can result from:

• A. decreased aldosterone secretion.
• B. increased ADH secretion.
• C. increased aldosterone secretion.
• D. decreased ADH secretion.

Correct answer: C

Rationale: The correct answer is C: increased aldosterone secretion. Aldosterone, a hormone produced by the adrenal glands, increases sodium reabsorption in the kidneys, leading to retention of sodium and water in the interstitial fluid. Increased aldosterone secretion enhances the reabsorption of sodium, thereby increasing its retention. Choice A is incorrect because decreased aldosterone secretion would lead to less sodium reabsorption and increased excretion. Choice B is incorrect because increased ADH secretion primarily affects water reabsorption rather than sodium. Choice D is incorrect because decreased ADH secretion would lead to increased water excretion but not necessarily affect sodium retention.

3. What is the main water-holding force in the blood capillaries?

• A. Capillary blood pressure
• B. Sodium in the blood plasma
• C. Protein in the blood plasma
• D. Chloride in the blood plasma

Correct answer: C

Rationale: The correct answer is C: Protein in the blood plasma. Plasma proteins, especially albumin, create oncotic pressure, which is the main force responsible for holding water within the blood capillaries. Capillary blood pressure (Choice A) is involved in pushing blood through the capillaries, while sodium and chloride in the blood plasma (Choices B and D) are electrolytes and do not play a significant role in the water-holding force within capillaries.

4. A nurse assesses a client who was started on intraperitoneal therapy 5 days ago. The client reports abdominal pain and feeling warm. For which complication of this therapy should the nurse assess this client?

• A. Allergic reaction
• B. Bowel obstruction
• C. Catheter lumen occlusion
• D. Infection

Correct answer: D

Rationale:

5. You are caring for a patient who is being treated on the oncology unit with a diagnosis of lung cancer with bone metastases. During your assessment, you note the patient complains of a new onset of weakness with abdominal pain. Further assessment suggests that the patient likely has a fluid volume deficit. You should recognize that this patient may be experiencing what electrolyte imbalance?

• A. Hypernatremia
• B. Hypomagnesemia
• C. Hypophosphatemia
• D. Hypercalcemia

Correct answer: D
