The nurse is administering Lithium to her patient. The nurse knows that Lithium is used to treat which of the following disorders?

Correct Answer: D

Rationale: Lithium is commonly used in the treatment of bipolar disorder, specifically for managing acute manic episodes and preventing future episodes of mania or depression. It helps stabilize mood and reduce the frequency and severity of mood swings in individuals with bipolar disorder. Lithium works by modulating neurotransmitter activity in the brain, particularly affecting the levels of serotonin and norepinephrine. It is not indicated for the treatment of hypertension, nausea, or thyroid disorders.

Correct Answer: C

Rationale: The most common side effect that occurs with the initial therapy of Nitroglycerine due to increased vasodilation is a headache. Nitroglycerine works by dilating blood vessels to improve blood flow to the heart. This sudden increase in vasodilation can lead to headache in many individuals, especially when starting the medication. The headache is often described as a pulsating sensation and usually subsides as the body adjusts to the medication. It is important to reassure patients that this side effect is temporary and tends to improve with continued use.

Correct Answer: A

Rationale: When administering Morphine, the typical starting dose for an adult is 2.5 mg to 10 mg every 3 to 4 hours as needed for pain. The dose should be adjusted according to the severity of the pain, the patient's response, and any side effects. Therefore, the correct choice is A, 2-5 mg every 3-4 hours, as it falls within the recommended starting dose range for Morphine administration.

Correct Answer: D

Rationale: Lithium is commonly used to treat bipolar disorder, a mental health condition characterized by mood swings that range from depressive lows to manic highs. Lithium helps stabilize these mood swings by altering the levels of certain chemicals in the brain. It is not used to treat hypertension, nausea, or thyroid disorders.

Correct Answer: C

Rationale: Omeprazole is a proton pump inhibitor commonly used to treat conditions such as acid reflux and ulcers. It is typically recommended to be taken in the morning on an empty stomach, at least 30 minutes before the first meal of the day. This is because omeprazole works best when the stomach is empty to ensure optimal absorption and effectiveness of the medication. Taking omeprazole with food or at other times of the day may reduce its potency and could lead to suboptimal results in managing the patient's condition.
