Nursing Elites

1. What is the transparent membrane that focuses the light entering the eyes onto the retina?

• A. Lens
• B. Sclera
• C. Cornea
• D. Pupils

Correct answer: A

Rationale: The correct answer is the lens. The lens is a transparent structure in the eye that helps to focus light onto the retina, which is essential for clear vision. The cornea and sclera are also important parts of the eye, but the lens specifically plays a crucial role in focusing light onto the retina. The sclera is the white outer layer of the eye that helps maintain the shape of the eye, while the cornea is the clear outer covering of the eye that helps to refract light into the eye.

2. Which of the following statements is incorrect about a patient with dysphagia?

• A. The patient will find pureed or soft foods, such as custards, easier to swallow than water
• B. Fowler’s or semi Fowler’s position reduces the risk of aspiration during swallowing
• C. The patient should always feed himself
• D. The nurse should perform oral hygiene before assisting with feeding

Correct answer: C

Rationale: The incorrect statement is that 'The patient should always feed himself.' Patients with dysphagia may require assistance with feeding due to difficulty in swallowing safely. It is essential to provide appropriate support and supervision during meal times to prevent complications such as aspiration or inadequate nutrition intake.

3. When administering digoxin 0.125 mg PO to an adult client, for which of the following findings should the nurse report to the provider?

• A. Potassium level 4.2 mEq/L.
• B. Apical pulse 58/min
• C. Digoxin level 1 ng/mL
• D. Constipation for 2 days

Correct answer: C

Rationale: Monitoring the digoxin level is crucial as it helps determine the drug's effectiveness and potential toxicity. A digoxin level of 1 ng/mL is within the therapeutic range. However, levels above this range can lead to toxicity, causing adverse effects like nausea, vomiting, visual disturbances, and dysrhythmias. Therefore, the nurse should report a digoxin level of 1 ng/mL to the provider for further evaluation and potential dose adjustment.

4. A healthcare provider is performing a gastric lavage for a client who has upper gastrointestinal bleeding. Which of the following actions should the healthcare provider take?

• A. Instill 500 ml of solution through the NG tube.
• B. Insert a large-bore NG tube.
• C. Use a cold irrigation solution.
• D. Instruct the client to lie on their right side.

Correct answer: B

Rationale: During a gastric lavage procedure for upper gastrointestinal bleeding, inserting a large-bore NG tube is essential to effectively remove gastric contents and blood. This tube allows for efficient irrigation and suction, aiding in the removal of harmful substances from the stomach. Instilling a large volume of solution or using a cold irrigation solution can lead to complications such as fluid overload or hypothermia. Instructing the client to lie on their right side is not directly related to the gastric lavage procedure.

5. A healthcare professional is reviewing ABG laboratory results of a client who is in respiratory distress. The results are pH 7.47, PaCO2 32 mm Hg, and HCO3 22 mm Hg. The healthcare professional should recognize that the client is experiencing which of the following acid-base imbalances?

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

Correct answer: B

Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.
