An older client receiving continuous tube feedings develops restlessness, agitation, and weakness. Which laboratory results are related to this finding, and should be reported to the health care provider immediately?

Glucose: 88 mg/dL

White Blood Cells (WBCs): 4000 (normal: 4,500- 11,000)

K+: 3.4 mEq/L

Na+: 154 mEq/L

Answer and Explanation

The Correct Answer is D

Choice A reason: This statement is false. Glucose: 88 mg/dL is a normal blood sugar level and does not indicate any problem with fluid or electrolyte balance¹.

Choice B reason: This statement is false. WBCs: 4000 is slightly below the normal range, but not significantly low. It may indicate a mild infection or inflammation, but not a serious fluid or electrolyte imbalance².

Choice C reason: This statement is false. K+: 3.4 mEq/L is slightly below the normal range, but not dangerously low. It may indicate a mild potassium deficiency, which can cause muscle weakness, but not restlessness or agitation.

Choice D reason: This statement is true. Na+: 154 mEq/L is above the normal range and indicates hypernatremia, or high blood sodium level. This can cause dehydration, confusion, restlessness, agitation, and seizures. It is a medical emergency that requires immediate treatment. Continuous tube feedings can increase the risk of hypernatremia if the formula is too concentrated or the fluid intake is inadequate⁵.

Correct Answer is C

Explanation

Choice A reason: I will always need to take hydrocortisone pills is a correct statement. Hydrocortisone is a synthetic form of cortisol, a hormone that is normally produced by the adrenal glands. After a bilateral adrenalectomy, the patient will have no adrenal glands and will need to take hydrocortisone pills for life to replace the missing hormone.

Choice B reason: I have a way to inject hydrocortisone in case of emergency is also a correct statement. Hydrocortisone injections are used to treat acute adrenal crisis, a life-threatening condition that can occur when the patient has low cortisol levels due to stress, illness, injury, or surgery. The patient should have an emergency kit with hydrocortisone injections and instructions on how to use them.

Choice C reason: I will stop taking hydrocortisone when I feel better is an incorrect statement. This indicates a need for further education regarding medications after a bilateral adrenalectomy. The patient should never stop taking hydrocortisone without consulting their doctor, as this can cause severe symptoms of adrenal insufficiency, such as low blood pressure, low blood sugar, weakness, fatigue, and confusion.

Choice D reason: I have nausea or vomiting often is a statement that requires further assessment by the nurse. Nausea or vomiting can be signs of inadequate or excessive hydrocortisone dosage, or other complications after a bilateral adrenalectomy. The nurse should monitor the patient's vital signs, blood glucose, electrolytes, and weight, and report any abnormal findings to the doctor. The patient may need to adjust their hydrocortisone dose or take other medications to manage their symptoms.

A. Lower your potassium (K+) level, and it will have a laxative side effect B. Lower your potassium (K+) and have a diuretic side effect C. Lower your sodium (Na+) and have a laxative side effect D. Lower your sodium (Na+) and cause diarrhea

Correct Answer is A

Explanation

Choice A reason: This statement is true. Kayexalate is a medication that binds to potassium in the colon and exchanges it for sodium, thereby lowering the blood potassium level. It also has a laxative effect, which helps to eliminate the excess potassium in the stool.

Choice B reason: This statement is false. Kayexalate does not have a diuretic effect, which means it does not increase urine output or fluid loss. Diuretics are medications that act on the kidneys and help to remove excess fluid and sodium from the body.

Choice C reason: This statement is false. Kayexalate does not lower the blood sodium level, but rather increases it. This is because it exchanges potassium for sodium in the colon, which adds more sodium to the bloodstream.

Choice D reason: This statement is false. Kayexalate does not cause diarrhea, but rather a laxative effect, which means it stimulates bowel movements and softens the stool. Diarrhea is a condition where the stool is watery and frequent, and can cause dehydration and electrolyte imbalance.
