Nursing Elites

1. A client with histoplasmosis has the following arterial blood gas (ABG) results: pH 7.30, PCO2 58 mm Hg, PO2 75 mm Hg, HCO3 27 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: The client's ABG results show a low pH (acidosis) and an elevated PCO2, indicating respiratory acidosis. In respiratory acidosis, there is inadequate excretion of CO2, leading to increased PCO2 levels and a decrease in pH. Therefore, the correct answer is 'Metabolic acidosis'. Choices B, C, and D are incorrect. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory acidosis involves low pH and high PCO2 levels, as seen in this case. Respiratory alkalosis is associated with high pH and low PCO2 levels.

2. 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.

3. A client is returning home after arthroscopy of the shoulder. The nurse should tell the client:

• A. To resume full activity the next day
• B. Not to eat or drink anything until the next morning
• C. To keep the shoulder completely immobilized for the rest of the day
• D. To report to the physician the development of fever or redness and heat at the site

Correct answer: D

Rationale: After arthroscopy, it is important for the client to report any signs of infection, such as the development of fever or redness and heat at the site, to the physician promptly. Options A, B, and C are incorrect. The client should not resume full activity the next day as rest and limited movement are usually recommended post-arthroscopy. It is not necessary to withhold food or fluids until the next morning; the client may resume the usual diet immediately unless otherwise instructed. While immobilization may be recommended for a period, keeping the shoulder completely immobilized for the rest of the day is not typically necessary post-arthroscopy.

4. When working with a large population of African-American clients at a community health center, which priority assessment should a nurse include?

• A. Measure height and weight.
• B. Assess blood pressure.
• C. Observe for any signs of abuse.
• D. Ask about medications.

Correct answer: B

Rationale: Assessing blood pressure is the priority assessment when working with a population of African-American clients due to the high prevalence of hypertension in this group. African Americans have a higher risk of hypertension, which can lead to complications like end-stage renal disease. Monitoring blood pressure allows for the early detection and management of hypertension. While measuring height and weight, observing for signs of abuse, and asking about medications are important assessments, assessing blood pressure is crucial in this context to address the specific health needs of African-American clients.

5. A female client taking oral contraceptives reports to the nurse that she is experiencing calf pain. What action should the nurse implement?

• A. Determine if the client has also experienced breast tenderness and weight gain.
• B. Encourage the client to begin a regular, daily program of walking and exercise.
• C. Advise the client to notify the healthcare provider for immediate medical attention.
• D. Tell the client to stop taking the medication for a week to see if symptoms subside.

Correct answer: C

Rationale: Calf pain is indicative of thrombophlebitis, a serious, life-threatening complication associated with the use of oral contraceptives which requires further assessment and possibly immediate medical intervention.
