A nurse is reviewing a client’s laboratory results prior to administering the client’s medications. The nurse notes that the client’s lithium level is 2.0 mEq/L.
Which of the following findings should the nurse expect?

Muscle irritability.

Constipation.

Hypoglycemia.

Increased BP.

Answer and Explanation

The Correct Answer is A

Muscle irritability. A client with a lithium level of

2.0 mEq/L has severe lithium toxicity, which can cause muscle irritability, tremors, seizures, and other neurological symptoms. The normal therapeutic range for lithium is 0.8-1.2 mEq/L.

Choice B is wrong because constipation is not a sign of lithium toxicity, but rather a possible side effect of lithium therapy at lower doses.

Choice C is wrong because hypoglycemia is not a sign of lithium toxicity, but rather a possible complication of diabetes or other conditions that affect blood sugar levels.

Choice D is wrong because increased blood pressure is not a sign of lithium toxicity, but rather a possible risk factor for cardiovascular disease or other conditions that affect blood vessels.

Correct Answer is B

Explanation

It occurs because nicotine stimulates the release of dopamine, a neurotransmitter that regulates mood and pleasure. When nicotine intake is stopped, dopamine levels drop and cause anxiety and irritability.

Choice A is wrong because tachycardia, or rapid heart rate, is not a symptom of nicotine withdrawal. In fact, smoking can increase blood pressure and heart rate, so quitting smoking may lower them.

Choice C is wrong because weight loss is not a symptom of nicotine withdrawal. On the contrary, weight gain is more likely to occur after quitting smoking, because nicotine suppresses appetite and increases metabolism.

Choice D is wrong because vomiting is not a symptom of nicotine withdrawal. Vomiting may be a side effect of some nicotine replacement therapies, such as patches or gum, but it is not caused by the lack of nicotine itself.

A. “My baby will be monitored for hypoglycemia after birth.” B. “I will check my blood glucose once every 8 hours.” C. “My baby is at risk for being underweight at birth.” D. “I should ensure that only 5 percent of my daily calories come from protein sources.”

Correct Answer is A

Explanation

This statement indicates an understanding of the teaching because babies born to mothers with gestational diabetes mellitus (GDM) are at risk for low blood sugar (hypoglycemia) after birth due to high insulin levels.

Choice B is wrong because a client who has GDM should check their blood glucose more frequently than once every 8 hours. The American Diabetes Association recommends checking blood glucose levels before meals and one hour after the start of each meal.

Choice C is wrong because a baby born to a mother with GDM is at risk for being overweight (macrosomia) at birth, not underweight. This can lead to complications such as shoulder dystocia, birth trauma, and cesarean delivery.

Choice D is wrong because a client who has GDM should ensure that about 15 to 20 percent of their daily calories come from protein sources, not 5 percent. Protein helps regulate blood glucose levels and supports fetal growth.
