Question 1 of 5
A nurse is caring for a client who has a new prescription for lorazepam. For which of the following adverse effects should the nurse monitor?
Correct Answer: B
Rationale:
Rationale: The correct answer is B, dizziness, because lorazepam is a benzodiazepine that can cause central nervous system depression, leading to dizziness as a common adverse effect. Urinary retention (
A) is not a common side effect of lorazepam. Decreased appetite (
C) is not typically associated with lorazepam use. Hypertension (
D) is not a common adverse effect of lorazepam. It is important to monitor for dizziness as it can affect the client's safety and mobility.
Question 2 of 5
A nurse is caring for a client who has been taking epoetin alfa for 3 months. Which of the following laboratory tests should the nurse monitor to determine the effectiveness of the medication?
Correct Answer: D
Rationale: The correct answer is D: Hgb (hemoglobin). Epoetin alfa is a medication used to stimulate red blood cell production. Monitoring hemoglobin levels is crucial to assess the effectiveness of the medication in increasing red blood cell count. Hemoglobin reflects the oxygen-carrying capacity of red blood cells, indicating if the medication is addressing the underlying anemia. Troponin (
A) is used to assess heart muscle damage, not relevant in this case. Thyroxine (
B) reflects thyroid function, not related to epoetin alfa therapy. Aspartate aminotransferase (AST) (
C) is a liver enzyme, not relevant for monitoring this medication's efficacy.
Question 3 of 5
A nurse is caring for a client who has a prescription for ceftriaxone. The nurse should monitor the client for which of the following adverse effects?
Correct Answer: B
Rationale: The correct answer is B: Maculopapular rash. Ceftriaxone is a cephalosporin antibiotic known to cause hypersensitivity reactions, including skin rashes like maculopapular rash. This type of rash is common with antibiotic use and may indicate an allergic reaction. Monitoring for this adverse effect is crucial to assess the client's response to the medication.
A: Concentrated urine is not a typical adverse effect of ceftriaxone.
C: Constipation is not a common adverse effect associated with ceftriaxone.
D: Pitting edema is not a recognized adverse effect of ceftriaxone.
Question 4 of 5
A nurse is preparing to administer regular and NPH insulin to a client. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: The correct answer is A: Withdraw the NPH insulin last. This is because regular insulin is a clear solution and should be withdrawn first to prevent contamination with the cloudy NPH insulin. Mixing the medications in a 3-mL syringe (
B) is not recommended as it may alter the effectiveness of the insulin. Administering the medications in two separate syringes (
C) is important to avoid mixing them prior to administration. Injecting air into the regular vial first (
D) is unnecessary and not a standard practice.
Question 5 of 5
A nurse is preparing to administer 17,000 units heparin subcutaneously. Available is heparin 20,000 units/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if applicable. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate the mL of heparin needed, use the formula: Amount needed (17,000 units) ÷ Concentration of heparin (20,000 units/mL) = mL to administer. 17,000 ÷ 20,000 = 0.85 mL (Round to the nearest hundredth).
Therefore, the correct answer is A (0.85 mL). Other choices are incorrect as they do not result from the correct calculation.
