A nurse is evaluating the central venous pressure (CVP) of a client who has sustained multiple traumas. Which of the following interpretations of a low CVP should the nurse make?

Fluid overload

Intracardiac shunt

Hypovolemia

Left ventricular failure

Answer and Explanation

The Correct Answer is C

Choice A Reason: This is incorrect because ﬂuid overload is a condition of excess ﬂuid volume in the body. A client who has ﬂuid overload is more likely to have a high CVP, which indicates increased pressure in the right atrium and vena cava.

Choice B Reason: This is incorrect because an intracardiac shunt is a condition of abnormal blood ﬂow between the chambers of the heart. A client who has an intracardiac shunt may have a normal or high CVP, depending on the direction and magnitude of the shunt.

Choice C Reason: This is correct because hypovolemia is a condition of low ﬂuid volume in the body. A client who has hypovolemia is more likely to have a low CVP, which indicates decreased pressure in the right atrium and vena cava.

Choice D Reason: This is incorrect because left ventricular failure is a condition of impaired pumping function of the left ventricle. A client who has left ventricular failure may have a normal or high CVP, depending on the degree of backward failure and pulmonary congestion.

Correct Answer is ["B","D","E"]

Explanation

Choice A Reason: This choice is incorrect because headache is not a common manifestation of ARF. Headache may be caused by various factors such as dehydration, stress, sinusitis, or migraine, but it does not indicate ARF.

Choice B Reason: This choice is correct because severe dyspnea is a common manifestation of ARF. Dyspnea is a difficulty or discomfort in breathing that aﬀects the oxygen delivery and carbon dioxide removal from the body. It may be caused by various factors such as lung disease, heart disease, anemia, or anxiety, but it indicates ARF when it is severe and persistent.

Choice C Reason: This choice is incorrect because nausea is not a common manifestation of ARF. Nausea is a sensation of uneasiness or discomfort in the stomach that may precede vomiting. It may be caused by various factors such as food poisoning, motion sickness, medication side eﬀects, or pregnancy, but it does not indicate ARF.

Choice D Reason: This choice is correct because hypotension is a common manifestation of ARF. Hypotension is a condition in which the blood pressure is lower than normal (less than 90/60 mm Hg). It may be caused by various factors such as dehydration, blood loss, sepsis, or shock, but it indicates ARF when it is due to reduced cardiac output or vasodilation from hypoxia.

Choice E Reason: This choice is correct because decreased level of consciousness is a common manifestation of ARF. Decreased level of consciousness is a condition in which the person has impaired awareness or responsiveness to stimuli. It may be caused by various factors such as brain injury, stroke, seizure, or drug overdose, but it indicates ARF when it is due to increased carbon dioxide levels (hypercapnia) or decreased oxygen levels (hypoxemia) in the brain.

A. Dextrose 5% in 0.9% sodium chloride B. Dextrose 5% in water C. 0.9% sodium chloride D. Lactated Ringer's

Correct Answer is D

Explanation

Choice A Reason: This is incorrect because dextrose 5% in 0.9% sodium chloride is a hypertonic solution that can cause ﬂuid overload and pulmonary edema in a client who has burns.

Choice B Reason: This is incorrect because dextrose 5% in water is a hypotonic solution that can cause ﬂuid shifts from the intravascular space to the interstitial space, resulting in hypovolemia and hypotension in a client who has burns.

Choice C Reason: This is incorrect because 0.9% sodium chloride is an isotonic solution that can cause hypernatremia and hyperchloremia in a client who has burns, as the ﬂuid loss from burns is greater than the sodium loss.

Choice D Reason: This is correct because lactated Ringer's is an isotonic solution that contains electrolytes similar to plasma, such as sodium, potassium, calcium, and chloride. It also contains lactate, which is converted to bicarbonate in the liver and helps correct the metabolic acidosis that occurs in a client who has burns.
