A nurse is providing teaching about a heart-healthy diet to a group of clients with hypertension. Which of the following statements by one of the clients indicates a need for further teaching?
"I may thicken gravies with cornstarch as I cook."
"Fresh fruits make a good snack option."
"I may eat 2 cans of soup a day."
"I will replace table salt with dried herbs."
The Correct Answer is C
A. Thicken gravies with cornstarch is acceptable as it does not add significant sodium and can be a healthier alternative to flour or other thickening agents.
B. Fresh fruits are indeed a healthy snack option and are encouraged in a heart-healthy diet due to their low sodium and high fiber content.
C. Eating 2 cans of soup a day is concerning because many canned soups are high in sodium, which can exacerbate hypertension. This statement indicates a need for further teaching about sodium intake.
D. Replacing table salt with dried herbs is a positive change that promotes flavor without adding sodium, aligning with heart-healthy dietary recommendations.

Correct Answer is A
Explanation
A. A private, negative-pressure room is essential for clients suspected of having tuberculosis (TB) to prevent airborne transmission. This setup helps contain airborne pathogens and protects other clients and staff.
B. A private, positive-pressure room is inappropriate for this situation because it is designed for immunocompromised patients, not those with potential infectious diseases.
C. A semi-private, negative-pressure room would not provide adequate isolation for a client with suspected TB, increasing the risk of transmission to another patient.
D. A semi-private, positive-pressure room is also inappropriate, as it poses a risk of spreading infectious agents to others in the facility.
Correct Answer is D
Explanation
A. Applying the pulse oximeter to a finger may not be ideal due to edema, which can affect the accuracy of the reading.
B. Using a skin fold is not a typical location for pulse oximetry and may not provide accurate readings.
C. Applying the probe to a toe may be less effective if the toenails are thickened, potentially affecting blood flow to that area and the accuracy of the reading.
D. The earlobe is a suitable alternative for measuring oxygen saturation, particularly in cases where peripheral sites (like fingers or toes) are compromised.
