A nurse is caring for a client who is receiving parenteral nutrition and identifies that the client has hyperkalemia. Which of the following actions should the nurse take?

Warm formula to room temperature.

Place the client on a cardiac monitor.

Administer IV dextrose.

Request a lactose-free formula.

Answer and Explanation

The Correct Answer is B

A. Warming the formula to room temperature would not address hyperkalemia.

B. Hyperkalemia can lead to cardiac dysrhythmias, so placing the client on a cardiac monitor

allows for continuous cardiac monitoring to detect any changes or abnormalities in heart rhythm.

C. Administering IV dextrose is not typically indicated for hyperkalemia. Instead, insulin may be administered with dextrose to promote cellular uptake of potassium.
D. Requesting a lactose-free formula is not relevant to the management of hyperkalemia.

Correct Answer is B

Explanation

A. Hyperactive bowel sounds: Muscarinic agonist poisoning typically results in increased gastrointestinal motility and hyperactive bowel sounds. Atropine, an anticholinergic medication, works by blocking muscarinic receptors and reducing gastrointestinal motility. Therefore, the presence of hyperactive bowel sounds may indicate ongoing muscarinic stimulation and inadequate treatment with atropine.
B. Heart rate 90/min: Atropine is an anticholinergic medication that increases heart rate by blocking the parasympathetic effects of acetylcholine on the heart. Bradycardia is a common manifestation of muscarinic agonist poisoning, and an increase in heart rate following atropine administration indicates reversal of this effect and effective treatment.
C. Blood pressure 90/50 mm Hg: Atropine administration may result in transient hypertension due to its effect on increasing heart rate and cardiac output. Hypotension is a common
manifestation of muscarinic agonist poisoning, and an increase in blood pressure following atropine administration may indicate improvement in cardiovascular function. Therefore, a blood pressure of 90/50 mm Hg may not necessarily indicate effective treatment with atropine.
D. Increased salivation: Muscarinic agonist poisoning typically results in excessive salivation (sialorrhea) due to stimulation of muscarinic receptors in the salivary glands. Atropine administration works by blocking these muscarinic receptors and reducing salivation. Therefore, increased salivation would indicate ongoing muscarinic stimulation and inadequate treatment with atropine.

A. "Do not chew more than 40 pieces of gum per day." B. "Allow 9 months for the gum to achieve the therapeutic effect." C. "Chew the gum slowly over 30 minutes." D. "Drink a glass of water 5 minutes before chewing the gum."

Correct Answer is C

Explanation

A. This statement is incorrect. While it’s essential not to exceed the recommended dose, the

maximum daily limit for nicotine gum is 24 pieces, not 40. Using more than the recommended amount can lead to adverse effects
B. This information is not accurate. Nicotine gum is typically used for a shorter duration. The

treatment plan varies, but it’s essential to follow the recommended dosing and gradually reduce usage over time. The goal is to quit smoking successfully, not to use the gum for 9 months
C. This advice is correct. Nicotine gum is not used like ordinary chewing gum. You should chew it a few times and then “park” it between your cheek and the space below your teeth. The nicotine is absorbed mostly in your mouth. Chewing it slowly over 30 minutes allows for
effective absorption and helps control withdrawal symptoms

D. Drinking water before chewing nicotine gum is not a necessary instruction for its use.
