1. A client requests information on the use of Feverfew. Which of the following responses should the nurse make?

A. It is used to treat skin infections.
B. It can decrease the frequency of migraine headaches.
C. It can lessen nasal congestion in the common cold.
D. It can relieve nausea of morning sickness during pregnancy.

Correct answer: B

Rationale: The correct response is B: Feverfew is commonly used to decrease the frequency of migraine headaches. However, it is important to note that it has not been proven to relieve an existing migraine headache. Choices A, C, and D are incorrect as Feverfew is not typically used for treating skin infections, lessening nasal congestion in the common cold, or relieving nausea of morning sickness during pregnancy.

2. A healthcare professional is preparing to administer clindamycin 200 mg by intermittent IV bolus. The amount available is clindamycin injection 200 mg in 100 mL 0.9% sodium chloride (0.9% NaCl) to infuse over 30 min. The healthcare professional should set the IV pump to deliver how many mL/hr?

A. 200 mL/hr
B. 150 mL/hr
C. 100 mL/hr
D. 250 mL/hr

Correct answer: A

Rationale: To calculate the flow rate in mL/hr: (Volume in mL / Time in hours) = Flow rate in mL/hr. In this case, (100 mL / 0.5 hr) = 200 mL/hr. The correct calculation is: 100 mL (volume) / 0.5 hr (time) = 200 mL/hr. Therefore, the correct answer is 200 mL/hr. Choice B (150 mL/hr), C (100 mL/hr), and D (250 mL/hr) are incorrect as they do not match the calculated flow rate needed for the administration of clindamycin.

3. Which medication is a beta blocker?

A. Atenolol (Tenormin)
B. Verapamil (Calan)
C. Captopril (Capoten)
D. Clopidogrel (Plavix)

Correct answer: A

Rationale: Atenolol (Tenormin) is a beta blocker commonly used to treat conditions like hypertension and angina by blocking the action of adrenaline on the heart. Verapamil is a calcium channel blocker, Captopril is an ACE inhibitor, and Clopidogrel is an antiplatelet medication. Therefore, the correct answer is Atenolol (Tenormin) as it belongs to the beta blocker class of medications.

4. A healthcare professional reviewing a client's health record notes a new prescription for Lisinopril 10 mg PO once daily. The healthcare professional should identify this as which of the following types of prescription?

A. Single
B. Stat
C. Routine
D. Standing

Correct answer: C

Rationale: A routine prescription indicates that the medication is to be administered on a regular schedule, typically daily, without a specified termination date or a specific number of doses. In this case, Lisinopril 10 mg PO once daily is to be given regularly until the healthcare provider decides to discontinue it. This type of prescription is common for medications that are part of the client's ongoing treatment regimen. The other choices are incorrect: 'Single' does not provide information about the frequency or duration of administration, 'Stat' indicates an urgent, one-time administration, and 'Standing' refers to a prescription that is automatically renewed without the need for a new order for each administration.

5. Which of the following is the antidote for benzodiazepine toxicity?

A. Flumazenil
B. Methylene blue
C. Deferoxamine
D. Alkalinize urine

Correct answer: A

Rationale: Flumazenil is the specific antidote for benzodiazepine toxicity. It acts as a competitive antagonist at the benzodiazepine binding site on the GABA receptor, reversing the sedative effects of benzodiazepines. Administration of flumazenil is indicated in cases of benzodiazepine overdose or toxicity to rapidly reverse the central nervous system depression caused by these drugs. It is important to note that flumazenil should be used cautiously in patients with a history of seizures or those who are physically dependent on benzodiazepines, as it can precipitate withdrawal symptoms or seizures.
