$CO = HR 	imes SV$

Question 6

A student nurse is asked to explain the principle of homeostasis. Which scenario best illustrates this concept?

Accepted Answer

The body increases insulin secretion after a meal to lower blood glucose levels.

Question 7

Which of the following best describes the role of the Theory of Human Caring (Watson) in nursing practice, as emphasized in the program outcomes?

Accepted Answer

It emphasizes the importance of caring relationships and holistic patient care.

Question 8

A patient presents with symptoms of metabolic acidosis. Which of the following equations is most relevant for evaluating their acid-base status?

Accepted Answer

$pH = -\log_{10} [H^+]$

Question 9

Which of the following is a direct application of the QSEN (Quality and Safety Education for Nurses) competencies in clinical practice?

Accepted Answer

Using evidence-based practice to improve patient outcomes.

Question 10

A nurse is evaluating a patient’s respiratory function. Which equation is used to calculate the partial pressure of oxygen in arterial blood ($PaO_2$)?

Accepted Answer

$PaO_2 = FiO_2 	imes (Patm - PH_2O) - PaCO_2 / R$

Question 11

Which of the following best demonstrates the integration of informatics and quality improvement in nursing practice?

Accepted Answer

Serum potassium ($K^+$)

Question 13

Which of the following is a key outcome of effective interprofessional collaboration in healthcare, as described in the program learning outcomes?

Accepted Answer

Improved patient safety and quality of care.

Question 14

A nurse is teaching a patient about diffusion and osmosis. Which statement is correct?

Accepted Answer

Osmosis is the movement of water across a semipermeable membrane from low to high solute concentration.

Question 15

A student is asked to calculate the mean arterial pressure (MAP) for a patient with a systolic blood pressure of 120 mmHg and a diastolic blood pressure of 80 mmHg. Which formula should they use?

Accepted Answer

$MAP = \frac{1}{3}(SBP - DBP) + DBP$

Question 16

Which of the following best describes the process of cell-to-cell communication in the human body?

Accepted Answer

Cells use chemical signals such as hormones and neurotransmitters to transmit information.

Question 17

A nurse is reviewing the stages of human aging. Which of the following is a physiological change commonly associated with aging?

Accepted Answer

Decreased skin elasticity

Question 18

A patient is experiencing hypovolemic shock. Which physiological response is most likely to occur as a compensatory mechanism?

Accepted Answer

Increased peripheral vasoconstriction
