The tendency of a drug to combine with its receptor is called:
- A. potency.
- B. efficacy.
- C. kinetics.
- D. affinity.
Correct Answer: D
Rationale: Affinity is a close relationship, mutual attraction, or similarity. The tendency of a drug to combine with its receptor is called affinity. Affinity is a measure of the strength of the drug-receptor bonding. Potency and efficacy describe the capability of a drug to produce the desired effect. Kinetics is the branch of science that deals with the effects of forces on the motions of material bodies or with changes in a physical or chemical system.

When planning for the physical assessment of the woman, the nurse ensures that which occurs?
- A. The woman is examined by a female health care provider.
- B. The woman's husband remains in the examining room at all times.
- C. The woman is examined without any other people in the examining room.
- D. Written permission is obtained from the woman to obtain subjective health data.
Correct Answer: A
Rationale: In many cultures, including Muslim, Hindu, and Latino, modesty is important, and exposure of a woman's genitals to men is considered demeaning. To respect the patient's cultural beliefs and modesty, it is best for a female health care provider to perform the examination. This practice helps to ensure the patient's comfort and adherence to cultural norms. Having the woman examined without any other people in the room (Choice C) may not address the cultural sensitivity required for this situation. Having the woman's husband remain in the examining room at all times (Choice B) may not align with the patient's cultural preferences and may cause discomfort. Written permission from the woman to obtain subjective health data (Choice D) is not directly related to ensuring a culturally sensitive physical assessment in this context.
The nurse, assisting with data collection of the abdomen, inspects the client’s abdomen. Which assessment technique should the nurse perform next?
- A. Percussion
- B. Auscultation
- C. Light palpation
- D. Deep palpation
Correct Answer: B
Rationale: The correct answer is auscultation. The assessment techniques used for a physical examination are inspection, palpation, percussion, and auscultation. These techniques are normally performed in this order. However, in the abdominal examination, auscultation is performed after inspection and before palpation and percussion. This order is specific to the abdomen because palpation and percussion can increase peristalsis, leading to a false interpretation of bowel sounds. Therefore, auscultation is performed before palpation and percussion in abdominal assessments to ensure accurate bowel sound assessment. Percussion and palpation are performed after auscultation in abdominal assessments. Choices A, C, and D are incorrect as auscultation is the next assessment technique to perform after inspection in abdominal assessments, followed by palpation and percussion.
A patient has just been prescribed Minipress to control hypertension. The nurse should instruct the patient to be observant of the following:
- A. Dizziness and light headed sensations
- B. Weight gain
- C. Sensory changes in the lower extremities
- D. Fatigue
Correct Answer: A
Rationale: Hypotension may be result of over correction of a hypertensive condition.
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.
Intramuscular (IM) phytonadione (vitamin K) 0.5 mg is prescribed for a newborn. After the medication is prepared, in which anatomic site does the nurse administer it?
- A. Rectus femoris muscle
- B. Deltoid muscle
- C. Gluteal muscle
- D. Vastus lateralis muscle
Correct Answer: D
Rationale: Vitamin K is administered to newborn infants to help prevent hemorrhagic disease. The best site for intramuscular injection in infants is the vastus lateralis muscle. This site is preferred due to its location away from the sciatic nerve, femoral artery, and vein, reducing the risk of complications. The rectus femoris muscle may be used if necessary; however, it is less favorable than the vastus lateralis due to its proximity to vital structures, making injections there more hazardous. The deltoid muscle is not typically used for IM injections in newborns. The gluteal muscles should be avoided until the child has been walking for at least a year, as they are poorly developed and close to the sciatic nerve.
