The nurse is preparing to assess the visual acuity of an adult patient, which of the following assessment should the nurse use for visual acuity
Perform the conduntation test
Ask the patient to read the point on a handheld larger card
Determine the patient's ability to read newsprint at a distance of 12 to 1 mche
Use the Snellen chart positioned 20 feet away from the patient
The Correct Answer is D
A. Perform the confrontation test:
The confrontation test is a basic visual field screening test. It assesses the peripheral vision by having the patient cover one eye and the examiner covers the opposite eye. The patient and the examiner then bring their fingers into the visual field from the periphery, and the patient indicates when they see the fingers.
B. Ask the patient to read the print on a handheld Jaeger card:
Jaeger cards are used for near vision testing. The patient reads progressively smaller print to assess their near vision acuity.
C. Determine the patient's ability to read newsprint at a distance of 12 to 14 inches:
This method assesses near vision. It is often used informally in clinical settings, where the patient is asked to read a newspaper or similar print at a comfortable reading distance.
D. Use the Snellen chart positioned 20 feet away from the patient:
The Snellen chart is a standardized chart used for visual acuity testing. It is placed 20 feet away from the patient, and the patient is asked to read the letters or symbols on the chart with one eye covered at a time.

Correct Answer is A
Explanation
A. AV node - SA node - bundle of His - bundle branches:
This sequence is incorrect. The SA node (sinoatrial node) initiates the electrical impulse in the heart, followed by the AV node (atrioventricular node), bundle of His, and then the bundle branches.
B. SA node - AV node - bundle of His - bundle branches:
This sequence is correct. The electrical stimulus of the cardiac cycle starts at the SA node, which is the natural pacemaker of the heart. From the SA node, the impulse travels to the AV node, then to the bundle of His, and finally to the bundle branches, which distribute the impulse to the ventricles, causing them to contract.
C. Bundle of His - AV node - SA node - Erb's Point:
This sequence is incorrect. Erb's Point is a point on the chest where heart sounds S2 and S3 can be heard most distinctly.
D. AV node - SA node - bundle of His - Erb's Point:
This sequence is incorrect. The AV node comes after the SA node in the electrical conduction system of the heart. Erb's Point is not a part of the normal cardiac conduction pathway; it is a location for auscultation on the chest.
Correct Answer is A
Explanation
A. When part of the lung is obstructed or collapsed: This statement is accurate. Unequal chest expansion can occur when part of the lung is obstructed or collapsed, preventing the affected area from expanding normally during inhalation.
B. When bulging of the intercostal spaces is present: This statement is not accurate. Unequal chest expansion typically refers to decreased expansion on one side, not bulging of intercostal spaces.
C. In an obese patient: This statement is not accurate. Obesity can affect breathing patterns and lung function, but it is not the primary cause of unequal chest expansion.
D. When accessory muscles are used to augment respiratory effort: This statement is not accurate. The use of accessory muscles to augment respiratory effort can be a sign of respiratory distress, but it doesn't directly cause unequal chest expansion. Unequal expansion is more indicative of specific lung conditions or issues with lung mechanics.
