The most common buffer system in the body is the:
Correct Answer: D
Rationale: The most common buffer system in the body is the bicarbonate-carbonic system. This system plays a crucial role in maintaining the pH balance in the blood. The bicarbonate ion (HCO3-) acts as a weak base, while carbonic acid (H2CO3) acts as a weak acid. The balance between these two components helps to regulate the pH of the blood.
Question 2 of 5
A 23 y.o. woman is seen at an outpatient clinic for a routine Pap smear. When questioned, she states she is deciding whether to engage in sexual activity with a man she is just getting to know. She asks how she can tell if he has an STD. Which response by the nurse is best?
Correct Answer: D
Rationale: The best response by the nurse is to recommend an examination by a physician with diagnostic testing as the only way to know if the potential partner is infection free. Simply relying on the appearance of cleanliness or condom use may not be sufficient to determine the presence of sexually transmitted infections (STIs) such as HPV, chlamydia, or herpes, which may not have visible symptoms. Encouraging regular testing and open communication about sexual health with partners is crucial in preventing the spread of STIs.

Correct Answer: B
Rationale: When caring for a client with hyperthyroidism, it is important to monitor the client for signs of restlessness, sweating, and excessive weight loss during thyroid replacement therapy. Treatment for hyperthyroidism often involves thyroid replacement therapy to restore the balance of thyroid hormones in the body. Monitoring for signs and symptoms of overmedication or undermedication is crucial to ensure the client's health and well-being. Restlessness, sweating, and weight loss can be indicators of an imbalance in thyroid hormone levels and may require adjustments in medication dosage. Regular monitoring and communication with healthcare providers are essential in managing the client's condition effectively.
Question 4 of 5
Which is the most appropriate vision acuity test for a child who is in preschool?
Correct Answer: C
Rationale: The HOTV chart is the most appropriate vision acuity test for a child who is in preschool. The HOTV chart is specifically designed for young children who may not yet know their letters. It uses simple shapes (H, O, T, V) instead of letters for visual acuity testing, making it more suitable and engaging for preschool-aged children. This chart allows for an accurate assessment of a child's visual acuity even before they are able to recognize letters, ensuring early detection of any vision problems that may affect their learning and development. The other options, such as the Cover test, Ishihara test, and Snellen letter chart, are more commonly used for older children and adults.
