Correct Answer: C

Rationale: To confirm pregnancy, the presence of palpable fetal movement is a positive indicator. Palpable fetal movement is a certain sign of pregnancy, known as a fetal movement felt by the examiner. Amenorrhea is a presumptive sign of pregnancy as it is reported by the woman but is not confirmatory. Thinning of the cervix (Hegar sign) is a probable sign of pregnancy, which is not confirmatory. A positive result on a home urine test for pregnancy is also a probable indicator. However, a positive pregnancy test result can sometimes yield false-positive results due to various factors like medication, recent pregnancy, or errors in reading.

Correct Answer: D

Rationale: The correct answer is that using a condom during intercourse can reduce the risk of STI transmission. Abstinence is a way to prevent STIs, but not the only way. Using a spermicide along with a condom can help prevent pregnancy, not STIs. While condoms may fail to prevent pregnancy, they are effective in reducing the risk of STI transmission. Therefore, using a latex condom for pregnancy prevention is not directly related to preventing the transmission of STIs.

Correct Answer: D

Rationale: The correct answer is 'Overarticulates words.' When communicating with a hearing-impaired client who may rely on lip-reading, it is essential to speak clearly at a normal rate and volume. Overarticulating words can distort lip movements, making it harder for the client to understand. Using short sentences helps in conveying information effectively, allowing the client time to process. While facial expressions and gestures provide additional visual cues that aid in communication, overarticulating words can be counterproductive in this scenario. Therefore, the nursing assistant should avoid overarticulating words to ensure clear and concise communication for the client.

Correct Answer: B

Rationale: To assess the fetal heart rate of a client who is 14 weeks pregnant, the nurse should use a Doppler transducer. Fetal heart sounds can be heard with a fetoscope by 20 weeks of gestation. The Doppler transducer amplifies fetal heart sounds so that they are audible by 10 to 12 weeks of gestation, making it the most appropriate choice for this scenario. Fetal heart sounds cannot be heard with a stethoscope. Pulse oximetry is not used to auscultate fetal heart sounds, so it is an incorrect choice in this context.

Correct Answer: B

Rationale: The correct answer is 'performing at the minimally acceptable level.' Quality is about meeting or exceeding customer requirements and expectations, as well as conforming to standards. The term 'performing at the minimally acceptable level' implies just meeting the minimum requirements, which falls short of the comprehensive definition of quality in terms of customer satisfaction and excellence. Therefore, this choice is the exception when defining quality. Choices A, C, and D align with the definition of quality as they all involve meeting or surpassing certain criteria for customer satisfaction and product excellence, which are essential components of quality management.
