Nursing Elites

1. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?

• A. The bicarbonate level (HCO3) is 31 mEq/L
• B. The arterial oxygen saturation (SaO2) is 92%
• C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
• D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg

Correct answer: D

Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.

2. A patient in the cardiac care unit is taking bumetanide (Bumex) for heart issues and is also diagnosed with Parkinson's Disease. An unlicensed assistive personnel is assisting with feeding the patient. Which of these foods should the nurse stress for the patient to eat most?

• A. Foods containing the least amount of salt
• B. Foods containing the most amount of potassium
• C. Foods containing the most amount of calories
• D. Foods containing the most amount of fiber

Correct answer: B

Rationale: Bumex is a loop diuretic that can lead to hypokalemia (low potassium levels). Hypokalemia can be dangerous and lead to various complications. To prevent a hypokalemic crisis, it is crucial to ensure an adequate intake of potassium. Therefore, the nurse should stress the patient to eat foods rich in potassium. Choices A, C, and D are not the priority in this situation. While monitoring salt intake is important in cardiac patients, the immediate concern with bumetanide use is the risk of hypokalemia, making choice B the most appropriate option.

3. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

4. The healthcare provider is reviewing the lab results of a patient who has presented in the Emergency Room. The lab results show that the BNP (B-type Natriuretic Peptide) value is 615 pg/ml. What would the healthcare provider take as the priority action?

• A. Call for a cardiac evaluation and implement appropriate measures
• B. Check the patient's oxygen saturation
• C. Inform the physician about the elevated BNP level
• D. Encourage the patient to limit physical activity

Correct answer: B

Rationale: An elevated BNP level is indicative of decreased cardiac output, suggesting potential heart failure. In this scenario, the priority action is to check the patient's oxygen saturation. Oxygen saturation assessment is crucial to ensure adequate oxygenation and respiratory function, which is essential in managing cardiac conditions. Calling for a cardiac evaluation and implementing appropriate measures may be necessary but is not the immediate priority without assessing oxygen saturation. Informing the physician about the elevated BNP level can be important for further management but is not the immediate action needed in this situation. Encouraging the patient to limit physical activity might be a consideration later but is not the priority action when dealing with a potential cardiac emergency.

5. A 4-year-old hospitalized child begins to have a seizure while playing with hard plastic toys in the hallway. Of the following nursing actions, which one should the nurse do first?

• A. Place the child in the nearest bed
• B. Administer IV medication to slow down the seizure
• C. Place a padded tongue blade in the child's mouth
• D. Remove the child's toys from the immediate area

Correct answer: D

Rationale: During a seizure, the priority nursing actions are to ensure the safety of the child and maintain airway patency. Placing objects in the child's mouth, like a padded tongue blade, is not recommended as it can lead to injury or obstruction of the airway. Moving the child to a bed is also not the immediate priority during a seizure. Administering IV medication to slow down the seizure is not typically done as the initial action. Therefore, the correct first nursing action is to remove any potential hazards, such as the hard plastic toys, from the immediate area to prevent injury during the seizure.
