Question 1 of 5
The basic metric unit for the measurement of volume :
Correct Answer: C
Rationale: The basic metric unit for the measurement of volume is the liter. Although all the other options are also units used for measuring volume, the liter is considered the basic metric unit. It is often used for measuring larger volumes of liquids or gases. The other options are subunits of a liter:
Question 2 of 5
Upon preparing to administer activated charcoal by mouth to treat a patient who took an overdose of aspirin and several unknown drugs, the nurse notes that the patient has become very somnolent and eyes open only to a noxious stimulus. Which action by the nurse is most appropriate at this point?
Correct Answer: A
Rationale: The patient's decreased level of consciousness (somnolence and only responding to noxious stimuli) indicates a potential deterioration in their condition, possibly due to the overdose. Activated charcoal is contraindicated in patients with an altered mental status due to the risk of aspiration. The nurse should immediately consult the nurse practitioner to reassess the patient's condition and determine the appropriate intervention, such as securing the airway or considering alternative treatments.
Question 3 of 5
A client is prescribed fluoxetine (Prozac) for depression. Which statement by the client indicates a need for further teaching?
Correct Answer: B
Rationale: Fluoxetine, an SSRI, treats depression but interacts with alcohol, worsening sedation or mood , indicating a teaching gap'clients must avoid it. Feeling better in weeks aligns with SSRI onset. Reporting suicidal thoughts is critical due to early risk. Morning dosing prevents insomnia. Drinking wine risks treatment failure or safety issues, critical in depression where stability is fragile. Further teaching must clarify this interaction, ensuring fluoxetine's efficacy and client well-being, making B the statement needing correction.
Question 4 of 5
A patient undergoing chemotherapy for breast cancer asks why she is not receiving trastuzumab like her sister. Which response by the nurse is correct?
Correct Answer: D
Rationale: Trastuzumab is a targeted therapy used specifically for HER2-positive breast cancer. If the patient's cancer cells do not overexpress the HER2 receptor, trastuzumab will not be effective. The decision to use targeted therapy is based on the molecular characteristics of the tumor, not the patient's age, insurance coverage, or estrogen receptor status. The nurse should explain that targeted therapies are tailored to the specific biology of the cancer, and trastuzumab is only appropriate for HER2-positive tumors.
Question 5 of 5
What is the antidote for Heparin?
Correct Answer: B
Rationale: Protamine is the antidote for Heparin. Heparin is an anticoagulant medication that prevents the formation of blood clots. In case of an overdose of Heparin or if there is a need to reverse its effects quickly (such as during surgery), Protamine is administered as the specific antidote. Protamine works by binding to Heparin and neutralizing its anticoagulant effects. Therefore, Protamine is the appropriate antidote to counteract the effects of Heparin.
