1. The healthcare professional is preparing to administer atenolol (Tenormin) to a client with angina. Which vital sign would cause the healthcare professional to question administering this drug?
- A. Respirations 12 breaths per minute
- B. Pulse 52 beats per minute
- C. Blood pressure 134/72
- D. Oxygen saturation 95%
Correct answer: B
Rationale: Atenolol is a beta-blocker medication that can lower heart rate. A pulse of 52 beats per minute is relatively low and administering atenolol could further decrease the heart rate, potentially leading to bradycardia. Monitoring the pulse rate and holding the medication if the pulse is below the prescribed parameters is crucial to prevent adverse effects such as bradycardia and hypotension.
2. A client has an infection and a prescription for gentamicin intermittent IV bolus every 8 hr. A peak and trough is required with the next dose. Which of the following actions should be taken to obtain an accurate gentamicin serum level?
- A. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
- B. Draw a peak level 90 min prior to administering the medication and a trough level 90 min after the dose.
- C. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
- D. Draw a peak level at 0900 and a trough level at 2100.
Correct answer: C
Rationale: To obtain an accurate gentamicin serum level, the trough should be drawn immediately before administering the medication, and the peak level should be drawn 30 minutes after the dose. This timing allows for the assessment of the lowest and highest drug concentrations in the bloodstream, ensuring therapeutic levels are achieved while minimizing the risk of toxicity. Choice A is correct as it follows this timing protocol. Choices B and D have incorrect timing for peak and trough levels, which would not provide an accurate representation of the drug's concentration in the bloodstream.
3. Which of the following conditions is not treated with Methotrexate?
- A. Sarcomas
- B. Leukemias
- C. Ectopic pregnancy
- D. Rheumatic fever
Correct answer: D
Rationale: The correct answer is D. Methotrexate is not typically used to treat rheumatic fever, which is more commonly managed with antibiotics to eradicate the underlying infection. Methotrexate is commonly used in the treatment of conditions like sarcomas, leukemias, and ectopic pregnancies due to its anti-inflammatory and anti-cancer properties.
4. A client has a Cerebrospinal fluid infection with gram-negative bacteria. Which of the following Cephalosporin antibiotics should be administered IV to treat this infection?
- A. Cefaclor
- B. Cefazolin
- C. Cefepime
- D. Cephalexin
Correct answer: C
Rationale: In treating a Cerebrospinal fluid infection caused by gram-negative bacteria, Cefepime, a fourth-generation cephalosporin, is the most suitable choice due to its enhanced efficacy against gram-negative organisms in such infections. Cefaclor (Choice A) is a second-generation cephalosporin more commonly used for respiratory tract infections. Cefazolin (Choice B) is a first-generation cephalosporin often used for skin and soft tissue infections. Cephalexin (Choice D) is a first-generation cephalosporin indicated for skin and urinary tract infections, but not the optimal choice for a Cerebrospinal fluid infection with gram-negative bacteria.
5. A client with angina is seeking a prescription for sildenafil to manage erectile dysfunction. Which of the following medications is contraindicated with Sildenafil?
- A. Aspirin
- B. Isosorbide
- C. Clopidogrel
- D. Atorvastatin
Correct answer: B
Rationale: Isosorbide, an organic nitrate used for angina, is contraindicated with sildenafil due to the risk of fatal hypotension. Concurrent use of these medications can lead to severe hypotension. Patients are advised to avoid taking nitrate medications for 24 hours after using isosorbide to prevent this dangerous interaction.
