Correct Answer: B

Rationale: The renal system plays a crucial role in regulating blood pressure through various mechanisms. Renin is an enzyme released by the kidneys in response to low blood pressure or low blood volume. Renin acts on angiotensinogen to convert it into angiotensin I, which is further converted into angiotensin II by angiotensin-converting enzyme (ACE) in the lungs. Angiotensin II is a potent vasoconstrictor, leading to an increase in blood pressure by constricting blood vessels. Additionally, angiotensin II stimulates the release of aldosterone, a hormone that promotes sodium and water retention in the kidneys, leading to an increase in blood volume and further elevating blood pressure. Therefore, the release of renin by the renal system ultimately leads to an increase in blood pressure.

Correct Answer: C

Rationale: Instructing the participant to track the relationship between urine color and activities would be the most appropriate response in this situation. Occasionally having pink urine can be caused by various factors, such as certain foods, medications, strenuous exercise, or even dehydration. By tracking when the urine appears pink in relation to these activities, the participant can gather valuable information to share with a healthcare provider if needed. This approach can help identify any patterns and determine the underlying cause, guiding further evaluation or management if necessary. It allows for a proactive and informative approach before seeking medical attention, as long as there are no other concerning symptoms present.

Correct Answer: A

Rationale: Consuming caffeinated coffee can potentially contribute to cardiac dysrhythmias in susceptible individuals. Caffeine is a stimulant that can increase heart rate and blood pressure, leading to arrhythmias in some people. Regular intake of caffeinated beverages can disrupt the normal electrical activity of the heart, especially in those with underlying cardiac conditions. Therefore, the nurse would identify drinking caffeinated coffee as a possible contributing factor to the client's dysrhythmia.

Correct Answer: A

Rationale: Disseminated intravascular coagulation (DIC) is a complex, life-threatening condition characterized by widespread activation of coagulation within the blood vessels. In the early stages of DIC, there is excessive clot formation (formation of small clots) throughout the body due to the dysregulation of coagulation factors. As the disease progresses, the body's clotting factors become depleted, leading to a state of systemic anticoagulation. This anticoagulant state increases the risk of hemorrhage (bleeding) as the blood is no longer able to adequately clot. Therefore, hemorrhage is a pathological change that occurs late in the course of DIC.
