Nokea
A nurse is caring for a client who has nausea and a prescription for metoclopramide intravenously every 8 hours as needed. The client asks the nurse how metoclopramide will relieve her nausea. Which explanation should the nurse provide?How does metoclopramide relieve nausea?
- A. The medication relieves nausea by promoting gastric emptying.
- B. The medication works by relaxing gastric muscles.
- C. The medication works by decreasing gastric acid secretions.
- D. The medication enhances gastric emptying.
Correct Answer: A,D
Rationale: The correct answers are A and D. Metoclopramide relieves nausea by promoting gastric emptying, which helps move food through the stomach faster. This action reduces the feeling of fullness and discomfort, ultimately alleviating nausea. Additionally, enhancing gastric emptying helps prevent reflux, which can contribute to nausea. Choices B and C are incorrect because metoclopramide does not work by relaxing gastric muscles or decreasing gastric acid secretions. These mechanisms do not directly address the issue of delayed gastric emptying, which is the primary reason for nausea relief with metoclopramide.

A provider has prescribed quetiapine 50 mg PO, divided equally every 12 hours for 3 days. The available medication is quetiapine 25 mg tablets. How many tablets should the nurse administer per dose on the third day? How many quetiapine tablets per dose on day 3?
- A. 1
- B. 2
- C. 3
- D. 4
Correct Answer: A
Rationale: The correct answer is A: 1 tablet. On the third day, the total dose required is 50 mg, which is equivalent to 2 tablets of 25 mg each. Since the dose needs to be divided equally every 12 hours, the nurse should administer 1 tablet per dose on the third day. Choice B (2 tablets) is incorrect as it would result in an overdose of 100 mg. Choices C (3 tablets) and D (4 tablets) are also incorrect for the same reason.
A nurse is caring for a child who is allergic to penicillin. Which prescription should the nurse verify with the provider?,Which prescription should be verified for a penicillin-allergic child?
- A. Amoxicillin-clavulanate.
- B. Gentamicin
- C. Erythromycin.
- D. Amphotericin
Correct Answer: A
Rationale: The correct answer is A: Amoxicillin-clavulanate. This is because amoxicillin-clavulanate belongs to the penicillin class of antibiotics and can potentially trigger an allergic reaction in a child who is allergic to penicillin. The nurse should verify this prescription with the provider to avoid any adverse reactions. Gentamicin (B) is an aminoglycoside antibiotic and is not related to penicillin. Erythromycin (C) is a macrolide antibiotic, which is also unrelated to penicillin. Amphotericin (D) is an antifungal medication and does not belong to the penicillin class. It is crucial for the nurse to ensure that the child does not receive any medication that could cause an allergic reaction due to their penicillin allergy.
A nurse is conducting a patient's history and physical examination. Which information should the nurse consider as subjective data? Which information is subjective data?
- A. Petechiae
- B. Nausea
- C. Cyanosis
- D. Fever
Correct Answer: B
Rationale: Subjective data is information provided by the patient based on their feelings, perceptions, or beliefs. Nausea falls under this category as it is a symptom that the patient experiences and reports subjectively. Petechiae, cyanosis, and fever are objective data as they can be observed or measured directly. Petechiae are small red or purple spots on the skin, cyanosis is a bluish discoloration of the skin due to lack of oxygen, and fever is an elevated body temperature, all of which can be confirmed through visual inspection or measurement. Therefore, choice B, nausea, is the correct answer as it relies on the patient's subjective experience.
A nurse has accepted a position on a pediatric unit and is learning about psychosocial development. Arrange Erikson's stages of psychosocial development in order from birth to adolescence. Arrange Erikson's stages from birth to adolescence.
- A. Identity vs. role confusion
- B. Trust vs. mistrust
- C. Industry vs. inferiority
- D. Autonomy vs. shame and doubt
- E. Initiative vs. guilt
Correct Answer: B,D,E,C,A
Rationale: 1. Trust vs. mistrust comes first as it pertains to infancy and the development of basic trust in caregivers.
2. Autonomy vs. shame and doubt follows, focusing on toddlers developing independence.
3. Initiative vs. guilt is next, focusing on preschoolers exploring and taking initiative.
4. Industry vs. inferiority is about school-aged children developing competence.
5. Identity vs. role confusion is about adolescents forming a sense of self.
Therefore, the correct order is B, D, E, C, A. Other choices are incorrect as they do not align with the chronological order of Erikson's stages.
A nurse in an emergency department is caring for a patient who has diabetic ketoacidosis (DKA) and a blood glucose level of 925 mg/dL. What prescription should the nurse anticipate from the provider? What prescription should the nurse anticipate for DKA?
- A. Glucocorticoid medications.
- B. Dextrose 5% in 0.45% sodium chloride.
- C. Oral hypoglycemic medications.
- D. 0.9% sodium chloride IV bolus.
Correct Answer: D
Rationale: The correct answer is D: 0.9% sodium chloride IV bolus. In DKA, the primary concern is severe dehydration and electrolyte imbalances due to high blood glucose levels. 0.9% sodium chloride helps to rehydrate the patient and correct electrolyte imbalances. Glucocorticoids (A) are not typically used in the treatment of DKA. Dextrose 5% in 0.45% sodium chloride (B) would worsen hyperglycemia. Oral hypoglycemic medications (C) are not appropriate for managing acute DKA. Therefore, the nurse should anticipate the prescription of 0.9% sodium chloride IV bolus to address the immediate needs of the patient with DKA.
