1. An allergic reaction is classified as what type of pharmacological effect?
- A. a therapeutic effect
- B. a side effect
- C. an adverse effect
- D. an incompatibility
Correct answer: an adverse effect
Rationale: An allergic reaction is classified as an adverse effect because it is an unintended response to a medication that requires treatment. A side effect is an undesired but somewhat expected reaction to a drug that does not necessarily need intervention. Incompatibility refers to an unsuitable combination of substances that leads to an adverse effect. A therapeutic effect is the desired and intended outcome of a medication.
2. A client needs to rapidly achieve a therapeutic plasma drug concentration of a medication. Rather than wait for steady state to be achieved, the physician might order:
- A. a maintenance dose.
- B. a loading dose.
- C. a medication with no first-pass effect.
- D. the medication to be given intravenously.
Correct answer: a loading dose.
Rationale: To rapidly achieve a therapeutic plasma drug concentration, a loading or priming dose is ordered. This dose quickly establishes the desired drug level. It is calculated by multiplying the volume of distribution by the desired plasma drug concentration. A maintenance dose, like choice A, is used to maintain the therapeutic level after the loading dose. Waiting for steady state without a loading dose would take five drug half-lives. Choice C, a medication with no first-pass effect, does not directly address the need for rapid attainment of therapeutic levels. While intravenous administration (choice D) offers excellent bioavailability, a single dose by this route may not achieve the desired therapeutic plasma concentration as rapidly as a loading dose.
3. The nurse is preparing a client for mammography. To prepare the client for a mammogram, the nurse should tell the client:
- A. To omit creams, powders, or deodorants before the exam
- B. To restrict fat intake for 1 week before the test
- C. That mammography replaces the need for self-breast exams
- D. That mammography requires a higher dose of radiation than an x-ray
Correct answer: To omit creams, powders, or deodorants before the exam
Rationale: The client undergoing a mammogram should be instructed to omit deodorants or powders beforehand because they can interfere with the imaging results. Answer A is correct as it aligns with the preparation needed before a mammogram to ensure accurate results. Answer B is incorrect because there is no requirement for fat intake restrictions before a mammogram. Answer C is incorrect because mammography does not replace the necessity of self-breast exams; both are crucial for maintaining breast health. Answer D is incorrect because a mammogram does not require higher doses of radiation than an x-ray. In fact, mammography uses a low dose of radiation to create images for breast examination.
4. A nurse provides instructions to a mother about crib safety for her infant. Which statement by the mother indicates a need for further instructions?
- A. ''Wood surfaces on the crib need to be free of splinters and cracks.''
- B. ''I need to keep large toys out of the crib.''
- C. ''The distance between the slats needs to be no more than 4 inches wide to prevent entrapment of my infant's head or body.''
- D. ''The drop side needs to be impossible for my infant to release.''
Correct answer: ''The distance between the slats needs to be no more than 4 inches wide to prevent entrapment of my infant's head or body.''
Rationale: The correct answer is, ''The distance between the slats needs to be no more than 4 inches wide to prevent entrapment of my infant's head or body.'' This statement indicates a need for further instructions as the distance between the slats should be no more than 2⅜ inches to prevent entrapment of the infant’s head and body, not 4 inches. Allowing a larger gap can pose a risk of entrapment or injury to the infant. Keeping large toys out of the crib is essential to prevent the infant from using them to climb out, which could result in serious injuries. Ensuring the drop side of the crib is impossible for the infant to release is crucial to prevent falls and injuries. Additionally, maintaining wood surfaces on the crib free of splinters, cracks, and lead-based paint is vital for the infant's safety and well-being.
5. How can the nurse promote relief of muscle pain, spasms, and tension?
- A. Encouraging the client to continue their activities as usual.
- B. Immobilizing the client.
- C. Applying heat, cold, pressure, or vibration to the painful area.
- D. Administering pain medication as needed to ease the muscle.
Correct answer: Applying heat, cold, pressure, or vibration to the painful area.
Rationale: To promote relief of muscle pain, spasms, and tension, the nurse should consider applying heat, cold, pressure, or vibration to the painful area. These interventions can help alleviate pain associated with muscle tension, pain, or spasms. Choice A is incorrect because encouraging the client to continue their activities as usual may exacerbate the pain. Choice B is incorrect as immobilizing the client may not address the underlying issue and could potentially lead to further complications. Choice D is also incorrect because while pain medication can be used, it is not the first-line treatment for muscle pain, spasms, and tension.
