Nursing Elites

1. An increase in capillary blood pressure would tend to:

• A. increase interstitial fluid volume.
• B. increase plasma volume.
• C. decrease interstitial fluid volume.
• D. increase plasma volume and decrease interstitial fluid volume.

Correct answer: A

Rationale: An increase in capillary blood pressure leads to a higher force pushing fluid out of the capillaries into the interstitial space, thereby increasing interstitial fluid volume. Choice B is incorrect because capillary blood pressure affects the movement of fluid into the interstitial space, not into the plasma. Choice C is incorrect as an increase in capillary blood pressure would not decrease interstitial fluid volume. Choice D is incorrect as it combines contradictory effects when capillary blood pressure increases.

2. The nurse caring for a patient post colon resection is assessing the patient on the second postoperative day. The nasogastric tube (NG) remains patent and continues at low intermittent wall suction. The IV is patent and infusing at 125 mL/hr. The patient reports pain at the incision site rated at a 3 on a 0-to-10 rating scale. During your initial shift assessment, the patient complains of cramps in her legs and a tingling sensation in her feet. Your assessment indicates decreased deep tendon reflexes (DTRs) and you suspect the patient has hypokalemia. What other sign or symptom would you expect this patient to exhibit

• A. Diarrhea
• B. Dilute urine
• C. Increased muscle tone
• D. Joint pain

Correct answer: B

Rationale:

3. A nurse is caring for a client with a peripheral vascular access device who is experiencing pain, redness, and swelling at the site. After removing the device, which action should the nurse take to relieve pain?

• A. Administer topical lidocaine to the site.
• B. Place warm compresses on the site.
• C. . Administer prescribed oral pain medication.
• D. Massage the site with scented oils.

Correct answer: B

Rationale:

4. A 73-year-old man who slipped on a small carpet in his home and fell on his hip is alert and oriented; PERRLA (pupils equally round and reactive to light and accommodation) is intact, and he has come by ambulance to the emergency department (ED). Heart rate elevated, he is anxious and thirsty. A Foley catheter is in place and 40mL of urine is present. The nurse's most likely explanation for the urine output is:

• A. The man urinated prior to his arrival in the ED and will probably not need to have the Foley catheter kept in place.
• B. The man has a brain injury, lacks ADH, and needs vasopressin.
• C. The man is in heart failure and is releasing atrial natriuretic peptide, which results in decreased urine output.
• D. He is having a sympathetic reaction, which has stimulated the renin-angiotensin-aldosterone system that results in diminished urine output.

Correct answer: D

Rationale: Renin is released by the juxtaglomerular cells of the kidneys in response to decreased renal perfusion. Angiotensin-converting enzyme converts angiotensin I to angiotensin II. Angiotensin II, with its vasoconstrictor properties, increases arterial perfusion pressure and stimulates thirst. As the sympathetic nervous system is stimulated, aldosterone is released in response to an increased release of renin, which decreases urine production. Based on the nursing assessment and mechanism of injury, this is the most likely cause of the lower urine output. Choices A, B, and C are incorrect because there is no indication of urination prior to arrival, brain injury, lack of ADH, or heart failure present in the scenario provided. The symptoms and context described point more towards a physiological response related to the sympathetic nervous system and the renin-angiotensin-aldosterone system rather than the other conditions mentioned.

5. A nurse is caring for an older adult client who is admitted with moderate dehydration. Which intervention should the nurse implement to prevent injury while in the hospital?

• A. Ask family members to speak quietly to keep the client calm.
• B. Assess urine color, amount, and specific gravity each day.
• C. Encourage the client to drink at least 1 liter of fluids each shift.
• D. Dangle the client on the bedside before ambulating.

Correct answer: D

Rationale: The correct answer is to 'dangle the client on the bedside before ambulating.' This intervention helps prevent orthostatic hypotension, a drop in blood pressure when changing positions, which is crucial in preventing falls and related injuries in older adult clients. Asking family members to speak quietly (Choice A) may help keep the client calm but does not directly address the risk of injury. Assessing urine parameters (Choice B) is important for monitoring hydration status but does not specifically prevent injury. Encouraging increased fluid intake (Choice C) is essential for managing dehydration but does not directly address the risk of injury during ambulation.
