Nursing Elites

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

• A. Optic
• B. Olfactory
• C. Oculomotor
• D. Trochlear

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 a maintenance dose of 5,000 units of subcutaneous heparin (an anticoagulant) daily. Nursing responsibilities for Mrs. Mitchell now include:

• A. Reviewing daily activated partial thromboplastin time (APTT) and prothrombin time.
• B. Reporting an APTT above 45 seconds to the physician
• C. Assessing the patient for signs and symptoms of frank and occult bleeding
• D. All of the above

Correct answer: D

Rationale: The correct answer is D. When a physician orders a maintenance dose of subcutaneous heparin, nursing responsibilities include reviewing daily activated partial thromboplastin time (APTT) and prothrombin time to monitor the patient's coagulation status, reporting an APTT above 45 seconds to the physician as it may indicate a risk of bleeding, and assessing the patient for signs and symptoms of frank and occult bleeding, which are potential adverse effects of anticoagulant therapy. Therefore, all the options listed are essential nursing responsibilities when a patient is on subcutaneous heparin therapy.

3. When planning care for a client on mechanical ventilation, which mode of ventilation that increases the effort of the client's respiratory muscles should NOT be included in the plan of care?

• A. Assist-control
• B. Synchronized intermittent mandatory ventilation
• C. Continuous positive airway pressure
• D. Pressure support ventilation

Correct answer: A

Rationale: Assist-control ventilation mode delivers a preset tidal volume at a set rate; however, it may not be suitable for clients who need to maintain some level of respiratory muscle activity. This mode provides full support for each breath, potentially leading to decreased respiratory muscle strength over time. Therefore, it is important to avoid using assist-control mode for clients who require increased effort of respiratory muscles to prevent muscle atrophy and promote optimal respiratory function.

4. How many milliliters are equal to 20 cc?

• A. 2
• B. 20
• C. 2000
• D. 20000

Correct answer: B

Rationale: 1 cc (cubic centimeter) is equal to 1 ml. Therefore, 20 cc is equal to 20 ml. To convert between cubic centimeters (cc) and milliliters (ml), the values are equivalent since they both measure volume in the metric system. Choice A (2) is incorrect as it does not account for the direct conversion between cc and ml. Choice C (2000) and choice D (20000) are incorrect as they represent conversions based on a misunderstanding of the relationship between cc and ml.

5. A client has a new diagnosis of tuberculosis and has been placed on a multi-medication regimen. Which of the following instructions should the nurse give the client related to ethambutol?

• A. Your urine can turn a dark orange.
• B. Watch for a change in the sclera of your eyes.
• C. Watch for any changes in vision.
• D. Take vitamin B6 daily.

Correct answer: C

Rationale: Ethambutol is associated with potential vision changes, including optic neuritis. Patients should be instructed to report any visual disturbances immediately to prevent permanent vision loss. Monitoring for changes in vision is crucial to detect any adverse effects early on and prevent serious complications.
