An amniocentesis is scheduled for a pregnant client in the third trimester. The nurse informs the client that the most common indication for amniocentesis during the third trimester is for which reason?
- A. Determination of whether alpha-fetoprotein (AFP) is present in the amniotic fluid
- B. Checking the amniotic fluid for intrauterine infection
- C. Determination of fetal lung maturity
- D. Checking the fetal cells for chromosomal abnormalities
Correct Answer: C
Rationale: The most common indication for amniocentesis in the third trimester is the determination of fetal lung maturity. This assessment is essential to evaluate the fetus's readiness for extrauterine life. Checking for alpha-fetoprotein (AFP) in the amniotic fluid is more commonly associated with midtrimester amniocentesis to identify chromosomal abnormalities. Assessing for intrauterine infection is not a primary reason for amniocentesis in the third trimester. While checking fetal cells for chromosomal abnormalities is a common indication for midtrimester amniocentesis, it is not the most common indication in the third trimester.

The home health nurse has made a visit to an 85-year-old female client's home who has recently had surgery to replace her left knee. The client has been discharged from a rehab facility and has been able to walk on her own. The nurse assesses the need for teaching related to fall prevention. What should the nurse include in this teaching plan?
- A. The client should remove all scatter rugs from the floor and minimize clutter.
- B. The client should not get up and move around the house.
- C. The client does not need to install a raised toilet and grab bar because she is able to walk on her own.
- D. The client should wear a robe and socks while walking in the house.
Correct Answer: A
Rationale: Rugs and clutter are a primary cause of falls in the home and should be eliminated if possible to decrease the risk of a fall.
When preparing to listen to a client's breath sounds, what technique should a nurse use?
- A. Ask the client to sit and lean forward slightly, with the arms resting comfortably across the lap.
- B. Listen to the right lung first, then the left lung, moving from top to bottom systematically.
- C. Ask the client to take deep breaths through the mouth.
- D. Use the diaphragm of the stethoscope, holding it firmly against the client's chest.
Correct Answer: D
Rationale: When preparing to listen to a client's breath sounds, a nurse should ask the client to sit and lean forward slightly, with the arms resting comfortably across the lap. The client should be instructed to breathe through the mouth a little more deeply than usual but to stop if feeling dizzy. The nurse should use the flat diaphragm end-piece of the stethoscope, holding it firmly on the chest wall. By using the diaphragm, the nurse can listen for at least one full respiration in each location, moving from side to side to compare sounds. This technique ensures a systematic and thorough assessment of lung sounds. Choice A is correct as it includes the proper positioning of the client and specifies the use of the diaphragm of the stethoscope. Choice B is incorrect as both lungs should be auscultated systematically, starting from the top and moving down. Choice C is incorrect as deep breaths, not shallow ones, are recommended for an accurate assessment of breath sounds.
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.
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 a 16-year-old girl visits the women's health clinic to obtain information about birth control because she is sexually active and wants to avoid pregnancy, what should the nurse do first when interviewing the client?
- A. Assess the client's knowledge of available birth control methods.
- B. Inform the client that birth control methods can be discussed without the client's boyfriend present.
- C. Tell the client that for her age and lifestyle, birth control pills would be one of the methods of contraception.
- D. Give the client written material about various birth control methods and ask her to read them and to call if she has any questions.
Correct Answer: A
Rationale: When a client seeks information about birth control, it is essential for the nurse to first assess the client's existing knowledge on the subject. This enables the nurse to provide tailored information that complements what the client already knows, facilitating better understanding and decision-making. Providing written material is a helpful educational tool but should not be the first intervention. Offering specific advice on birth control methods based on age and lifestyle limits the client's autonomy and decision-making process. Mentioning the client's boyfriend as a requirement for discussing birth control is inappropriate and nontherapeutic, as the client should be able to seek information independently.
