The nurse is discussing the blood flow pattern of the heart. The nurse should recognize which of the following as the accurate blood flow pattern of the heart?

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.

A. Maxillary sinusitis:

Explanation: The client's symptoms of facial pain, fever, malaise, swollen turbinates, purulent nasal discharge, and dull, throbbing pain in the cheeks and teeth on the right side, especially when palpated, are indicative of maxillary sinusitis. Maxillary sinusitis refers to the inflammation of the maxillary sinuses, which are located in the cheek area. The symptoms described align with a bacterial infection in this sinus.

B. Nasal polyps:

Explanation: Nasal polyps are soft, noncancerous growths on the lining of the nasal passages or sinuses. While they can cause nasal congestion and a runny nose, they do not typically present with the specific symptoms mentioned in the scenario, such as facial pain, fever, and purulent discharge.

C. Frontal sinusitis:

Explanation: Frontal sinusitis involves inflammation of the frontal sinuses located in the forehead area. Symptoms may include forehead pain, headache, and nasal discharge. However, the described symptoms in the scenario (dull, throbbing pain in the cheeks and teeth on the right side) are more characteristic of maxillary sinusitis.

D. Posterior epistaxis:

Explanation: Posterior epistaxis refers to a nosebleed that originates from the back of the nose, often due to bleeding from the sphenopalatine artery. While nosebleeds can cause blood drainage into the throat and result in a metallic taste, the other symptoms described in the scenario, such as facial pain, fever, and purulent discharge, are not indicative of posterior epistaxis.
