A nurse is caring for a client who sustained blood loss. Which of the following is a manifestation of hypovolemia?
Decreased heart rate
Increased blood pressure
Weak pulse
Dyspnea
The Correct Answer is C
Choice A reason: Decreased heart rate is not a manifestation of hypovolemia. Hypovolemia is a condition where there is a decreased volume of blood in the body, which can result from blood loss, dehydration, or fluid shifts. Hypovolemia can cause the heart rate to increase, not decrease, as the body tries to compensate for the low blood pressure and maintain adequate perfusion.
Choice B reason: Increased blood pressure is not a manifestation of hypovolemia. Hypovolemia can cause the blood pressure to decrease, not increase, as the blood volume and cardiac output are reduced. The body may try to constrict the blood vessels to increase the blood pressure, but this is usually not enough to overcome the effects of hypovolemia.
Choice C reason: Weak pulse is a manifestation of hypovolemia. Hypovolemia can cause the pulse to become weak, thready, or difficult to palpate, as the blood flow and pressure are diminished. The pulse may also become irregular or rapid, as the heart tries to pump faster and harder to deliver oxygen to the tissues.
Choice D reason: Dyspnea is not a specific manifestation of hypovolemia. Dyspnea is a term for difficulty breathing, which can have many causes, such as asthma, pneumonia, or pulmonary edema. Hypovolemia can cause dyspnea if it leads to shock, which is a life-threatening condition where the organs and tissues are not receiving enough oxygen. However, dyspnea alone is not enough to indicate hypovolemia.

Correct Answer is C
Explanation
Choice A reason: This is not the best response because it is alarmist and does not address the client's concern. The nurse should not assume that the client needs to have their medications adjusted or be admitted to the hospital without further assessment.
Choice B reason: This is not the best response because it is inaccurate and does not explain the link between urine retention and confusion. The nurse should not imply that the client is causing their own confusion by not drinking enough water.
Choice C reason: This is the best response because it is accurate and educates the client on the effects of dehydration on the body. The nurse should encourage the client to drink more fluids throughout the day and offer strategies to make it easier for them to access the bathroom at night.
Choice D reason: This is not the best response because it is irrelevant and does not address the client's dehydration. The nurse should not suggest that the client has a urinary tract infection without evidence or testing. The nurse should also not discourage the client from urinating at night, as this can lead to other complications.
Correct Answer is B
Explanation
Choice A reason: Normal saline is not contraindicated for a dehydrated client with a skull fracture. Normal saline is an isotonic solution that has the same concentration of solutes as the blood plasma. It can help restore fluid balance and prevent cerebral edema.
Choice B reason: Dextrose in water 5% is contraindicated for a dehydrated client with a skull fracture. Dextrose in water 5% is a hypotonic solution that has a lower concentration of solutes than the blood plasma. It can cause fluid to shift from the blood vessels into the brain cells, increasing the intracranial pressure and worsening the skull fracture.
Choice C reason: Lactated Ringer's (LR) is not contraindicated for a dehydrated client with a skull fracture. Lactated Ringer's (LR) is an isotonic solution that has the same concentration of solutes as the blood plasma. It can also provide electrolytes such as sodium, potassium, calcium, and lactate, which can help correct acid-base imbalances.
Choice D reason: Dextrose in normal saline is not contraindicated for a dehydrated client with a skull fracture. Dextrose in normal saline is a hypertonic solution that has a higher concentration of solutes than the blood plasma. It can cause fluid to shift from the brain cells into the blood vessels, reducing the intracranial pressure and cerebral edema.
