Question 1 of 5
A client is receiving Total Parenteral Nutrition (TPN) while admitted in the inpatient setting. Which of the following conditions can occur if the nurse abruptly stops TPN?
Correct Answer: B
Rationale: The correct answer is B: Hypoglycemia. Abruptly stopping TPN can lead to hypoglycemia because the body has been dependent on the continuous infusion of glucose from the TPN solution for energy. When TPN is stopped suddenly, there is a rapid drop in blood sugar levels, leading to hypoglycemia.
A: Diarrhea is not a common consequence of abruptly stopping TPN.
C: Hypovolemia is unlikely as TPN is primarily a source of nutrition and not fluid replacement.
D: Erythema at the site is a localized reaction and not a systemic effect of stopping TPN.
Question 2 of 5
The nurse is caring for an 18-year-old client who has recently been prescribed montelukast. Which statement made by the client indicates understanding of the newly prescribed medication?
Correct Answer: C
Rationale:
Rationale:
Choice C is correct because montelukast is a long-term asthma medication. The client understanding this indicates awareness of the medication's purpose and duration.
Choice A is incorrect as anaphylaxis is not a common side effect of montelukast.
Choice B is incorrect as bloodwork monitoring is not routinely required for this medication.
Choice D is incorrect as self-medicating without medical advice can be harmful.
Question 3 of 5
A client is taking pyridostigmine for muscle weakness associated with myasthenia gravis. The nurse educates the client on which possible cholinergic side effects associated with this medication? (Select all that apply)
Correct Answer: B,D,F
Rationale:
Correct
Answer: B, D, F
Rationale:
- Dry mouth (choice
A) is not a common cholinergic side effect of pyridostigmine.
- Diarrhea (choice
B) is a possible cholinergic side effect due to increased GI motility.
- Decreased urination (choice
C) is not a typical cholinergic side effect.
- Excessive lacrimation (choice
D) can occur due to increased stimulation of the lacrimal glands.
- Tachycardia (choice E) is not a common cholinergic side effect.
- Excessive sweating (choice F) can occur as a result of increased cholinergic activity leading to stimulation of sweat glands.
Question 4 of 5
The nurse is caring for a client currently taking oxymetazoline. Which of the following statements should the nurse include regarding oxymetazoline?
Correct Answer: A
Rationale: The correct answer is A: Limit use of the drug to 3 days to prevent rebound nasal congestion. Oxymetazoline is a topical decongestant used to relieve nasal congestion. Prolonged use can lead to rebound congestion, where the nasal passages become more congested when the medication is stopped. Limiting use to 3 days helps prevent this rebound effect.
Choice B is incorrect as oxymetazoline is not known to cause drowsiness, so it can be taken at any time.
Choice C is incorrect because the effects of oxymetazoline are usually seen within minutes, not a week.
Choice D is incorrect as oxymetazoline is not used for asthma but for nasal congestion.
Question 5 of 5
A client newly prescribed niacin (Nicotinic Acid) presents to the healthcare setting with complaints of flushing following doses. Which of the following medications would the nurse anticipate being administered?
Correct Answer: C
Rationale: The correct answer is C: NSAIDs. Niacin causes flushing due to prostaglandin release. NSAIDs, which inhibit prostaglandin synthesis, can help alleviate this side effect. A: Beta Blockers and B: Calcium Channel Blockers do not directly target the mechanism of niacin-induced flushing. D: Fibric Acid Derivatives are used to lower triglycerides, not for flushing.
