The nurse is assessing a client receiving peritoneal dialysis. Which laboratory result should immediately be reported to the primary healthcare provider (PHCP)?
Calcium 8.6 mg/dL
WBC 19,000 mm3
Serum pH 7.33
Hemoglobin 9 mg/dL
The Correct Answer is B
Choice A rationale: A calcium level of 8.6 mg/dL is within the normal range.
Choice B rationale: An elevated white blood cell count (WBC) of 19,000 mm3 indicates a potential infection or inflammatory process, requiring immediate attention, especially in a client receiving peritoneal dialysis.
Choice C rationale: A serum pH of 7.33 is within the normal range.
Choice D rationale: A hemoglobin level of 9 mg/dL might indicate anemia, but in a client receiving dialysis, it might not require immediate reporting unless it significantly drops further.

Correct Answer is A
Explanation
Choice A rationale: This is the correct answer. It corresponds to 300 mg of the drug ((300x 5)/250).
Choice B rationale: This is incorrect because it is too low. It is the amount of milliliters that corresponds to 200 mg of amoxicillin trihydrate, which is less than the prescribed dose of 300 mg.
Choice C rationale: This is incorrect because it is too low. It is the amount of milliliters that corresponds to 60 mg of amoxicillin trihydrate, which is not enough to treat an oral infection.
Choice D rationale: This is incorrect because it is too low. It is the amount of milliliters that corresponds to 250 mg of amoxicillin trihydrate, which is less than the prescribed dose of 300 mg.

Correct Answer is C
Explanation
Choice A rationale: Low blood pressure sensed by baroreceptors in the kidneys would stimulate the renin-angiotensin-aldosterone system, which regulates blood pressure and sodium balance.
Choice B rationale: Low osmolality sensed by osmoreceptors in the kidneys would
indicate that the body has excess water and needs to excrete it, which would inhibit ADH release.
Choice C rationale: ADH, or antidiuretic hormone, is a peptide hormone that regulates the water balance in the body. It is released from the posterior pituitary gland in response to signals from the hypothalamus. When the plasma osmolarity, or the concentration of solutes in the blood, is high, it means that the body is dehydrated and needs to conserve water. The osmoreceptors in the hypothalamus detect this change and stimulate the release of ADH, which acts on the kidneys to increase water
reabsorption and decrease urine output. This helps to lower the plasma osmolarity and restore the water balance.
Choice D rationale: High concentration of potassium sensed by chemoreceptors in the carotid body would affect the acid-base balance and respiratory rate, but not ADH
release.
