Nursing Elites

1. A nurse is preparing to measure a client's level of oxygen saturation and observes edema of both hands and thickened toenails. The nurse should apply the pulse oximeter probe to which of the following locations?

• A. Finger
• B. Earlobe
• C. Toe
• D. Skin fold

Correct answer: B

Rationale: When a client has edema of both hands and thickened toenails, these conditions can impede accurate readings from the finger and toe locations. The earlobe is the best alternative site for the pulse oximeter probe in this scenario. Placing the probe on the earlobe will help ensure a more accurate measurement of oxygen saturation despite the issues with the hands and toenails. Therefore, the correct answer is to apply the pulse oximeter probe to the earlobe. Choices A, C, and D are incorrect because of the potential limitations presented by the edema and thickened toenails.

2. A client with pneumonia is receiving oxygen therapy. Which of the following oxygen delivery devices should be used to deliver a precise oxygen concentration?

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

Correct answer: C

Rationale: A Venturi mask should be used to deliver a precise oxygen concentration to a client with pneumonia. Venturi masks are designed to deliver a specific oxygen concentration by mixing oxygen with room air in a precise ratio. This device is ideal for patients who require accurate oxygen delivery, such as those with chronic lung diseases. Nasal cannulas deliver a lower concentration of oxygen and are more suitable for patients with mild respiratory issues. Simple face masks and non-rebreather masks do not provide as precise control over the oxygen concentration as a Venturi mask.

3. What is the most appropriate action for a healthcare professional to take when a medication error occurs?

• A. Document the error in the patient's medical record.
• B. Report the error to the healthcare provider immediately.
• C. Apologize to the patient and explain what happened.
• D. Continue administering the medication and monitor the patient closely.

Correct answer: B

Rationale: When a medication error occurs, the most appropriate action for a healthcare professional is to report the error to the healthcare provider immediately. This is crucial for ensuring prompt corrective action to mitigate any potential harm to the patient. Documenting the error is important but should come after reporting it to the relevant authorities. Apologizing to the patient is important for maintaining trust and communication but should not take precedence over reporting and addressing the error. Continuing to administer the medication without addressing the error is unsafe and goes against patient safety protocols.

4. A nurse is preparing to administer ampicillin 500 mg IV bolus every 6 hours. Available is ampicillin 500 mg in 50 mL dextrose 5% in water (D5W) to infuse over 20 minutes. The nurse should set the IV pump to deliver how many mL/hr?

• A. 100 mL/hr
• B. 150 mL/hr
• C. 200 mL/hr
• D. 250 mL/hr

Correct answer: B

Rationale: To infuse 50 mL over 20 minutes, the pump should be set to 150 mL/hr. This calculation ensures the correct rate for the infusion of the medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the given information.

5. A nurse is monitoring an older adult female client who had a myocardial infarction (MI) for the development of an acute kidney injury (AKI). Which of the following findings should the nurse identify as indicating an increased risk of AKI?

• A. Magnesium 2.0 mEq/L
• B. Blood urea nitrogen (BUN) 20 mg/dL
• C. Serum Osmolality 290 mOsm/kg H2O
• D. Serum creatinine 1.8 mg/dL

Correct answer: D

Rationale: An elevated serum creatinine level (1.8 mg/dL) is a significant indicator of potential kidney impairment. In acute kidney injury (AKI), serum creatinine levels rise due to decreased kidney function, reflecting the kidneys' inability to effectively filter waste from the blood. Magnesium level, BUN, and serum osmolality are not direct indicators of kidney function or risk of AKI. Magnesium levels are more related to electrolyte balance, BUN can be affected by factors other than kidney function, and serum osmolality reflects the concentration of solutes in the blood, not specifically kidney function.
