A client is to begin a 6-month course of therapy with isoniazid. The nurse should plan to provide which information to the client?

Avoid vitamin supplements during therapy.

Drink alcohol in small amounts only.

Report yellow eyes or skin immediately.

Increase intake of Swiss or aged cheeses.

Answer and Explanation

The Correct Answer is C

A. Avoid vitamin supplements during therapy: This is not generally advised for isoniazid therapy. In fact, vitamin B6 supplements are often recommended to prevent peripheral neuropathy caused by isoniazid.

B. Drink alcohol in small amounts only: Alcohol can increase the risk of liver toxicity when taking isoniazid. It is typically advised to avoid alcohol altogether during treatment.

C. Report yellow eyes or skin immediately: Isoniazid can cause liver toxicity, which can lead to jaundice (yellowing of the eyes and skin). This is a serious side effect and should be reported immediately to prevent further liver damage.

D. Increase intake of Swiss or aged cheeses: This recommendation is not related to isoniazid therapy. Aged cheeses are more relevant to patients on monoamine oxidase inhibitors (MAOIs) due to tyramine content.

Correct Answer is B

Explanation

A. Bradypnea, or abnormally slow breathing, is not typically associated with hypoxia. Hypoxia usually triggers an increase in respiratory rate (tachypnea) as the body attempts to take in more oxygen to meet its needs.
B. Cyanosis, a bluish discoloration of the skin and mucous membranes, is a key sign of hypoxia. It occurs when there is insufficient oxygen in the blood, leading to a darker color of deoxygenated hemoglobin. Cyanosis is most commonly observed in the lips, fingertips, and toes.
C. Pallor, or paleness of the skin, can occur in various conditions but is not specific to hypoxia. It is more commonly associated with anemia or shock rather than low oxygen levels in the blood.
D. Bradycardia, or a slower-than-normal heart rate, is not typically a manifestation of hypoxia. Instead, hypoxia often causes tachycardia as the body attempts to increase oxygen delivery to tissues by pumping blood more quickly.

A. The client has developed confusion. B. The client's serum sodium is 140 mEq/L (135 to 145 mEq/L). C. The client has a positive Chvostek's sign. D. The client's blood urea nitrogen (BUN) level is 18 mg/dL (10 to 20 mg/dL).

Correct Answer is A

Explanation

A. The client has developed confusion: Hypotonic fluids can cause a rapid shift of water into cells, potentially leading to cerebral edema. This can manifest as confusion or altered mental status, which is a serious adverse effect requiring immediate attention.

B. The client's serum sodium is 140 mEq/L (135 to 145 mEq/L): A serum sodium level within the normal range indicates that the hypotonic fluid therapy is likely effective in correcting hypernatremia, and does not suggest an adverse effect.

C. The client has a positive Chvostek's sign: A positive Chvostek's sign is indicative of hypocalcemia rather than an adverse effect of hypotonic fluid administration. This sign is related to low calcium levels and is not a direct result of hypotonic fluid therapy.

D. The client's blood urea nitrogen (BUN) level is 18 mg/dL (10 to 20 mg/dL): This BUN level is within normal limits and does not suggest an adverse effect of hypotonic fluid therapy. BUN levels can be affected by various factors, but this value alone is not indicative of an adverse reaction.
