Nursing Elites

1. A patient is being treated for shock after a motor vehicle accident. The provider orders 6% dextran 75 to be given intravenously. The nurse should expect which outcome as the result of this infusion?

• A. Decreased urine output
• B. Improved blood oxygenation
• C. Increased interstitial fluid
• D. Stabilization of heart rate and blood pressure

Correct answer: D

Rationale: 6% Dextran 75 is a high molecular-weight colloidal solution used to treat shock from burns or trauma. Colloids like 6% dextran 75 are plasma expanders that help increase blood volume, leading to improved heart rate and blood pressure stabilization. The infusion of plasma expanders does not typically decrease urine output. It primarily aims to stabilize circulation rather than affect blood oxygenation or increase interstitial fluid levels.

2. Following the diagnosis of angina pectoris, a client reports being unable to walk up two flights of stairs without pain. Which of the following measures would most likely help the client prevent this problem?

• A. Climb the stairs early in the day.
• B. Rest for at least an hour before climbing the stairs.
• C. Take a nitroglycerin tablet before climbing the stairs.
• D. Lie down after climbing the stairs.

Correct answer: C

Rationale: The correct answer is to take a nitroglycerin tablet before climbing the stairs. Nitroglycerin helps prevent angina by dilating the coronary arteries, which increases blood flow to the heart. This medication can help reduce the chest pain and discomfort experienced during physical exertion. Climing the stairs early in the day (Choice A) does not address the underlying issue of inadequate blood flow to the heart. Resting for at least an hour before climbing the stairs (Choice B) may not be as effective in preventing angina as taking nitroglycerin. Lying down after climbing the stairs (Choice D) does not offer a preventive measure for angina; it is more focused on post-activity rest rather than prevention.

3. In a patient with asthma, which of the following is the most important indicator of respiratory function?

• A. Oxygen saturation.
• B. Respiratory rate.
• C. Arterial blood gases.
• D. Peak expiratory flow rate.

Correct answer: D

Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.

4. A nurse checks the residual volume from a client’s nasogastric tube feeding before administering an intermittent tube feeding and finds 35 mL of gastric contents. What should the nurse do before administering the prescribed 100 mL of formula to the client?

• A. Pour the residual volume into the nasogastric tube through a syringe with the plunger removed
• B. Discard the residual volume properly and record it as output on the client’s fluid balance record
• C. Dilute the residual volume with water and inject it into the nasogastric tube, applying pressure on the plunger
• D. Mix the residual volume with the formula and pour it into the nasogastric tube, using a syringe without a plunger

Correct answer: A

Rationale: After checking the residual feeding contents, the nurse should pour the residual volume back into the stomach by removing the syringe bulb or plunger and then pouring the gastric contents, using the syringe, into the nasogastric tube. This helps ensure that the residual volume is reintroduced into the client's gastrointestinal tract. Option B is incorrect because discarding the residual volume without reinstilling it into the stomach can lead to inaccurate medication administration and potential electrolyte imbalances. Option C is incorrect as diluting the residual volume with water and injecting it under pressure can cause aspiration or discomfort for the client. Option D is incorrect because mixing the residual volume with the formula can alter the prescribed dosage and consistency, potentially affecting the client's nutritional intake and causing complications.

5. After checking the urinary drainage system for kinks in the tubing, the nurse determines that a client who has returned from the post-anesthesia care has a dark, concentrated urinary output of 54 ml for the last 2 hours. What priority nursing action should be implemented?

• A. Report the findings to the surgeon.
• B. Irrigate the indwelling urinary catheter.
• C. Apply manual pressure to the bladder.
• D. Increase the IV flow rate for 15 minutes.

Correct answer: A

Rationale: In this situation, the nurse's priority action should be to report the findings to the surgeon. An adult should typically produce about 60 ml of urine per hour, so a dark, concentrated, and low urine output of 54 ml over 2 hours raises concerns. This change in urine output may indicate issues such as dehydration, renal problems, or inadequate fluid intake. Reporting this finding to the surgeon is crucial to ensure appropriate evaluation and intervention. Irrigating the catheter, applying manual pressure to the bladder, or increasing the IV flow rate are not appropriate actions based on the information provided and could potentially worsen the situation.
