A nurse is teaching a client who has angina about a new prescription for sublingual nitroglycerin tablets. Which of the following instructions should the nurse include in the teaching?

"Keep the tablets at room temperature in their original glass bottle."

"Discard any tablets you do not use every 6 months."

"Take one tablet each morning 30 minutes prior to eating."

"Place the tablet between your cheek and gum to dissolve

Answer and Explanation

The Correct Answer is D

A. "Keep the tablets at room temperature in their original glass bottle." This is a correct storage instruction. Nitroglycerin tablets are sensitive to heat and light, so they should be stored in their original container, protected from light, and kept at room temperature.

B. "Discard any tablets you do not use every 6 months." This is not an accurate instruction. Nitroglycerin tablets usually have an expiration date printed on the label, and they should be discarded after that date.

C. "Take one tablet each morning 30 minutes prior to eating." This is not an accurate instruction. Sublingual nitroglycerin is taken as needed to relieve angina symptoms, not on a regular schedule like a daily medication.

D. "Place the tablet between your cheek and gum to dissolve."

Sublingual nitroglycerin tablets are used to relieve angina symptoms by causing vasodilation, which increases blood flow to the heart muscle. To take sublingual nitroglycerin tablets effectively, the client should be instructed to place the tablet between the cheek and gum to dissolve. This allows the medication to be absorbed through the mucous membranes in the mouth and enter the bloodstream quickly, providing rapid relief from angina symptoms.

Correct Answer is A

Explanation

A. Morphine 6 mg IV push every 3 hr PRN acute pain:
This choice is correct. It accurately transcribes the medication name (morphine), the dosage (6 mg), the route (IV push), the frequency (every 3 hours), and the indication (PRN for acute pain).
B. Morphine 6.0 mg IV push every 3 hr PRN acute pain:
This choice is not incorrect, but it is unnecessary to include the trailing zero in the dosage (6.0 mg). Both "6" and "6.0" indicate the same value, and omitting the decimal point is common practice in medication dosages.
C. MS 6 mg IV push every 3 hr PRN acute pain:
This choice is incorrect. "MS" is an abbreviation for "morphine sulfate," but it's not widely used in modern healthcare settings. Using the full name "morphine" is clearer and less prone to confusion.
D. MSO4 6 mg IV push every 3 hr PRN acute pain:
This choice is incorrect. "MSO4" is the chemical symbol for morphine sulfate. While it's a valid abbreviation, it's not as commonly used as the full name "morphine." Using the full name of the medication is clearer and more familiar to healthcare professionals.

A. Hypomagnesemia B. Hyponatremia C. Hypocalcemia D. Hypokalemia

Correct Answer is B

Explanation

A. Hypomagnesemia:
Correct Answer: This electrolyte imbalance is the one the nurse should assess the client for.
Explanation: Lithium is primarily excreted by the kidneys, and its excretion can be influenced by factors that affect renal function, including electrolyte imbalances. Hypomagnesemia (low magnesium levels) can potentially reduce the excretion of lithium, leading to increased lithium levels in the blood. This can increase the risk of lithium toxicity, which can be dangerous. Therefore, monitoring magnesium levels is important in clients taking lithium.
B. Hyponatremia:
Incorrect Explanation: While hyponatremia (low sodium levels) is a potential concern, it is not as directly linked to lithium interaction as hypomagnesemia.
Explanation: Lithium can cause diabetes insipidus, which leads to excessive urination and subsequent loss of water and electrolytes, including sodium. However, hyponatremia is not the immediate electrolyte imbalance that arises due to the interaction with lithium.
C. Hypocalcemia:
Incorrect Explanation: Hypocalcemia (low calcium levels) is not a primary concern in the context of lithium use.
Explanation: Lithium does not have a direct interaction with calcium levels. Hypocalcemia is typically not a result of lithium use or its interaction with other factors.
D. Hypokalemia:
Incorrect Explanation: While electrolyte imbalances like hypokalemia (low potassium levels) can have health implications, it is not the primary electrolyte imbalance to be concerned about with lithium use.
Explanation: Hypokalemia is not a direct consequence of lithium interaction. Monitoring potassium levels is important for overall health, but it's not the primary electrolyte imbalance associated with lithium use and its potential interactions.
