Nursing Elites

1. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63mmHg, HCO3 23, and oxygenation saturation (SAO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?

• A. tuberculosis (TB)
• B. pneumonia
• C. pleural effusion
• D. hypoxia

Correct answer: D

Rationale: A combined low PO2 and low SAO2 indicates hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low because hypoxia stimulates hyperventilation, but the best analysis in this case is hypoxia due to the combination of low PO2 and low SAO2.

2. Nurses should understand the chain of infection because it refers to:

• A. the linkages involved in disease transmission.
• B. the sequence required for transmission of disease.
• C. the clustering of bacteria in a specific pattern.
• D. increasing virulence patterns among microorganisms.

Correct answer: B

Rationale: The chain of infection refers to the sequence required for the transmission of disease, involving steps like the pathogen's presence, movement from a reservoir, and entry into a susceptible host. Understanding this sequence helps healthcare professionals, including nurses, in implementing effective infection control measures. Choices A, C, and D are incorrect because they do not accurately describe the concept of the chain of infection. Choice A is too broad and does not specifically address the sequential nature of disease transmission. Choice C focuses on bacterial clustering rather than the transmission process. Choice D mentions virulence patterns, which are not the primary focus of the chain of infection concept.

3. A nurse gave medications to the wrong client. She stated the client responded to the name called. What is the nurse's appropriate documentation?

• A. Note in medication records the drug given
• B. The client was not hurt, no need for documentation
• C. Note the client's orientation
• D. Completely fill out an incident report

Correct answer: D

Rationale: In the case where medications are given to the wrong client, the appropriate documentation by the nurse should involve completely filling out an incident report. This report is essential for tracking errors, implementing corrective measures, and ensuring patient safety. Choice A is incorrect because solely noting the drug given does not address the severity of the error. Choice B is incorrect because even if the client was not hurt, documentation is crucial for quality improvement and risk prevention. Choice C is incorrect as noting the client's orientation does not adequately address the medication error and its implications.

4. Which of the following symptoms is most characteristic of a client with lung cancer?

• A. exertional dyspnea
• B. persistent changing cough
• C. air hunger; dyspnea
• D. cough with night sweats

Correct answer: B

Rationale: The most characteristic symptom of lung cancer is a persistent changing cough. This cough may worsen over time and may produce blood-tinged sputum. Exertional dyspnea (Choice A) is more common in chronic obstructive pulmonary disease (COPD) due to airway obstruction. Air hunger and dyspnea (Choice C) are more typical of conditions like asthma. Cough with night sweats (Choice D) is commonly associated with tuberculosis rather than lung cancer.

5. After administering enoxaparin (Lovenox) subcutaneously into the abdomen, which action should the nurse take?

• A. Gently rub the injection site after removing the needle
• B. Have the client maintain a side-lying position for at least five minutes
• C. Remove the needle and engage the needle safety device
• D. Apply heat to the injection site

Correct answer: C

Rationale: After administering a subcutaneous injection of enoxaparin (Lovenox) into the abdomen, the nurse should remove the needle and engage the needle safety device. Rubbing the injection site after the needle is withdrawn is not recommended as it may cause irritation and bruising. Having the client maintain a side-lying position for at least five minutes is unnecessary for a subcutaneous injection into the abdomen. Applying heat to the injection site is not indicated after administering enoxaparin subcutaneously; it could increase the risk of bleeding or bruising at the injection site.
