What is a chemical reaction between drugs before their administration or absorption known as?
- A. a drug incompatibility
- B. a side effect
- C. an adverse event
- D. an allergic response
Correct Answer: A
Rationale: A chemical reaction between drugs before their administration or absorption is termed a drug incompatibility. This phenomenon commonly occurs when drug solutions are mixed before intravenous administration but can also happen with orally administered drugs. Choices B, C, and D are incorrect because side effects, adverse events, and allergic responses typically occur after the drugs have been administered and absorbed, not before.

A nurse is explaining a nonstress test to a pregnant client. The nurse explains that the results are nonreactive if which finding is noted on the electronic monitoring recording strip?
- A. Two fetal heart accelerations within a 20-minute period, peaking at 15 beats/min above baseline and lasting 15 seconds from baseline to baseline
- B. Accelerations without fetal movement with fetal heart rate (FHR) increases of 15 beats/min for 15 seconds
- C. Acceleration of the FHR by 25 to 30 beats/min for at least 15 seconds in response to fetal movement
- D. Absence of accelerations after fetal movement
Correct Answer: D
Rationale: The correct answer is 'Absence of accelerations after fetal movement.' In a nonreactive (nonreassuring) stress test, the monitor recording would not show accelerations after fetal movement within a 40-minute period. This absence of accelerations indicates a nonreactive result. Choices A, B, and C describe different patterns of fetal heart rate accelerations that are not indicative of a nonreactive result in a nonstress test, making them incorrect. Choice A describes the characteristics of a reactive (reassuring) result, where there should be at least two fetal heart accelerations within a 20-minute period, peaking at least 15 beats/min above the baseline, and lasting 15 seconds from baseline to baseline. Choice B incorrectly states 'Accelerations without fetal movement,' which is contradictory. Choice C describes an acceleration response to fetal movement, which does not signify a nonreactive result.
A nurse monitoring a newborn infant notes that the infant's respirations are 40 breaths/min. On the basis of this finding, what is the most appropriate action for the nurse to take?
- A. Contacting the registered nurse
- B. Documenting the findings
- C. Wrapping an extra blanket around the infant
- D. Placing the infant in an oxygen tent
Correct Answer: B
Rationale: The normal respiratory rate of a newborn infant is 30 to 60 breaths/min, with an average of 40. Since the infant's respiratory rate falls within the normal range, the most appropriate action for the nurse is to document the findings. Contacting the registered nurse, placing the infant in an oxygen tent, or wrapping an extra blanket around the infant are unnecessary actions as the respiratory rate is normal. Documenting the findings is important to provide a record of the assessment and serve as a baseline for future comparisons if needed.
While taking the vital signs of a pregnant client admitted to the labor unit, a nurse notes a temperature of 100.6°F, pulse rate of 100 beats/min, and respirations of 24 breaths/min. What is the most appropriate nursing action based on these findings?
- A. Notify the registered nurse of the findings.
- B. Document the findings in the client's medical record.
- C. Recheck the vital signs in 1 hour.
- D. Continue collecting subjective and objective data.
Correct Answer: A
Rationale: The correct answer is to notify the registered nurse of the findings. In a pregnant client, the normal temperature range is 98°F to 99.6°F, with a pulse rate of 60 to 90 beats/min and respirations of 12 to 20 breaths/min. A temperature of 100.4°F or higher, along with an increased pulse rate and faster respirations, suggests a possible infection. Immediate notification of the registered nurse is crucial for further evaluation and intervention. While documenting the findings is essential, the priority lies in promptly escalating abnormal vital signs for assessment and management. Rechecking vital signs in 1 hour may delay necessary interventions for a deteriorating condition. Continuing to collect data is relevant but should not delay informing the registered nurse when abnormal vital signs are present.
The chemotherapeutic DNA alkylating agents such as nitrogen mustards are effective because they:
- A. cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA.
- B. have few, if any, side effects.
- C. are used to treat multiple types of cancer.
- D. are cell-cycle-specific agents.
Correct Answer: A
Rationale: Alkylating agents are highly reactive chemicals that introduce alkyl radicals into biologically active molecules and thereby prevent their proper functioning, replication, and transcription. Choice 2 is incorrect because alkylating agents have numerous side effects including alopecia, nausea, vomiting, and myelosuppression. Choice 3 is incorrect because nitrogen mustards have a broad spectrum of activity against chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and breast and ovarian cancer, but they are effective chemotherapeutic agents because of DNA crosslinkage. Choice 4 is incorrect because alkylating agents are non-cell-cycle-specific agents.
During a routine health screening, the nurse should talk to the parents of a 1-year-old child about which of the following?
- A. the potential hazards of accidents
- B. appropriate nutrition now that the child has been weaned from breast-feeding
- C. toilet training
- D. how to purchase appropriate shoes now that the child is walking
Correct Answer: A
Rationale: Accidents are the primary source of injury in children and can be life threatening. Appropriate nutrition should have been discussed during the weaning process and while the purchase of appropriate shoes is important, it is not life threatening. One year of age is too early to discuss toilet training.
