1. The client was asked to read the Snellen chart. Which of the following is being tested?

Correct answer: A

Rationale: The correct answer is A: Optic. The Snellen chart is used to test visual acuity, which assesses the function of the optic nerve responsible for vision. Choices B, C, and D are incorrect. Olfactory relates to the sense of smell, oculomotor controls eye movement, and trochlear controls certain eye muscles. Therefore, the only option related to vision testing in this context is the optic nerve.

2. The physician orders the administration of high-humidity oxygen by face mask and placement of the patient in a high Fowler’s position. After assessing Mrs. Paul, the nurse writes the following nursing diagnosis: Impaired gas exchange related to increased secretions. Which of the following nursing interventions has the greatest potential for improving this situation?

Correct answer: D

Rationale: Chest physiotherapy is the most effective intervention in cases of impaired gas exchange related to increased secretions. This technique helps mobilize and clear secretions from the airways, thereby improving gas exchange in the lungs. Placing a humidifier or administering oxygen by high humidity face mask may provide moisture but may not directly address the clearance of secretions. Encouraging increased fluid intake can help with hydration but may not address the underlying issue of impaired gas exchange due to secretions.

3. A healthcare professional is preparing to administer an autologous blood product to a client. Which of the following actions should the professional take to identify the client?

Correct answer: A

Rationale: When preparing to administer an autologous blood product, it is crucial to correctly identify the client to prevent errors. Matching the client's blood type with the type and cross-match specimens ensures that the blood product is intended for the correct recipient. This step helps in verifying the patient's identity and avoiding any transfusion-related complications. Confirming the blood type through type and cross-matching is a standard practice to ensure patient safety during blood transfusions.

4. After routine patient contact, how long should hand washing last at least?

Correct answer: A

Rationale: Proper hand washing for 30 seconds is recommended after routine patient contact as it effectively removes pathogens. This duration ensures thorough cleaning without excessive time consumption, promoting infection control and prevention.

5. Which of the following interventions is considered the most effective form of universal precautions?

Correct answer: B

Rationale: The most effective form of universal precautions is to discard all used uncapped needles and syringes in an impenetrable protective container. This practice minimizes the risk of needle-stick injuries, which are a significant concern when dealing with used needles. By safely disposing of uncapped needles, healthcare providers can protect themselves and others from potential exposure to bloodborne pathogens.
