Question 1 of 5
During a routine check-up, the nurse evaluates a client with rheumatoid arthritis. To assess for the most obvious disease manifestations first, the nurse checks for:
Correct Answer: C
Rationale: When evaluating a client with rheumatoid arthritis, the nurse should check for joint abnormalities first because it is the most obvious manifestation of the disease. Rheumatoid arthritis primarily affects the joints, causing inflammation, pain, stiffness, and potentially deformity over time. Assessing for joint abnormalities can provide crucial information about the severity and progression of the disease, guiding further assessment and intervention plans. Muscle weakness, painful subcutaneous nodules, and gait disturbances can also be present in rheumatoid arthritis, but joint abnormalities are the hallmark feature that should be assessed initially.

Question 3 of 5
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 4 of 5
Which following parameters correlates best with measurements of the body's total protein stores?
Correct Answer: D
Rationale: Upper arm circumference has been found to correlate best with measurements of the body's total protein stores. This anthropometric measurement is often used as an indicator of nutritional status, particularly protein reserves such as muscle mass. Skinfold thickness can provide information about body fat levels, while height and weight may not specifically indicate protein stores as accurately as upper arm circumference.
Question 5 of 5
The nurse is talking to a parent of an infant with heart failure about feeding the infant. Which statement about feeding the child is correct?
Correct Answer: A
Rationale: In infants with heart failure, they may have increased metabolic demands due to their condition. Thus, it may be necessary to increase the caloric density of the infant's formula to ensure adequate nutrition and energy intake. This can help support the infant's growth and provide the necessary energy for their increased metabolic needs. Increasing the amount of formula or feeding too frequently (every 2 hours) may not be necessary and could lead to other issues like overfeeding. Placing a nasal oxygen cannula on the infant during and after each feeding (Option D) is not typically related to feeding practices for an infant with heart failure.
