A nurse in a clinic is talking with a client who has a new diagnosis of osteoarthritis. The nurse should anticipate that the client will require teaching about which of the following medications?

Choice A reason: Hypertension
Hypertension, or high blood pressure, is not typically an expected finding in hypovolemic shock. In fact, one would expect the opposite, hypotension, due to the decreased circulating blood volume. Hypertension might be present in the initial stages due to compensatory mechanisms, but as the condition progresses, blood pressure usually drops.

Choice B reason: Bradypnea
Bradypnea, or abnormally slow breathing, is not a common finding in hypovolemic shock. Instead, tachypnea, or rapid breathing, may be observed as the body attempts to compensate for reduced oxygen delivery to tissues.

Choice C reason: Oliguria
Oliguria, or low urine output, is an expected finding in hypovolemic shock. As the blood volume decreases, the kidneys receive less blood flow, leading to reduced urine production. This is a protective mechanism to conserve body fluids, but it also indicates the severity of fluid loss and the need for urgent intervention.

Choice D reason: Flushing of the skin
Flushing of the skin is not an expected finding in hypovolemic shock. Instead, the skin may appear pale, cool, and clammy due to vasoconstriction and reduced blood flow to the periphery as the body prioritizes blood flow to vital organs.

Choice A reason:
This choice suggests a pH of 7.50, which is indicative of alkalosis, and not typically expected in a client with chronic kidney disease (CKD). CKD often leads to metabolic acidosis due to the accumulation of acids in the body as the kidneys fail to excrete them. The HCO₃⁻ level of 20 mEq/L is slightly lower than the normal range (22-26 mEq/L), and the PaCO₂ of 32 mm Hg is within the normal range (35-45 mm Hg), but these values do not align with the expected acidosis associated with CKD.

Choice B reason:
This set of values is consistent with metabolic acidosis, which is commonly seen in clients with CKD. A pH of 7.25 indicates acidemia, and an HCO₃⁻ level of 19 mEq/L is below the normal range, suggesting a primary metabolic acidosis. The PaCO₂ of 30 mm Hg is at the lower end of the normal range, which may indicate a compensatory respiratory response to the metabolic acidosis.

Choice C reason:
A pH of 7.30, while on the lower side, is not as acidic as one would expect in a client with CKD. The HCO₃⁻ level of 26 mEq/L is within the normal range, and a PaCO₂ of 50 mm Hg suggests respiratory acidosis, which is not the primary disorder in CKD.

Choice D reason:
This choice indicates a pH of 7.55, which is too alkaline and not characteristic of CKD, where metabolic acidosis is the expected finding. An HCO₃⁻ level of 30 mEq/L is higher than the normal range, suggesting metabolic alkalosis. The PaCO₂ of 31 mm Hg is slightly below the normal range, possibly indicating a compensatory response, but it does not align with the metabolic acidosis typically seen in CKD.
