A nurse is reinforcing teaching with a 36-year-old client who is at 16 weeks of gestation and is scheduled for an amniocentesis. The nurse should include in the teaching that an amniocentesis is performed to identify which of the following findings?
Chromosomal abnormalities
Placental circulation
Rh incompatibility
Fetal breathing movements
The Correct Answer is A
Rationale:
A. Chromosomal abnormalities: Amniocentesis involves analyzing amniotic fluid to detect genetic and chromosomal disorders such as Down syndrome, trisomy 18, and neural tube defects. It is typically performed between 15 and 20 weeks gestation for diagnostic accuracy during this stage of fetal development.
B. Placental circulation: Assessment of placental blood flow and circulation is usually done via Doppler ultrasound, not amniocentesis. Amniocentesis does not evaluate the vascular function or perfusion status of the placenta.
C. Rh incompatibility: While amniocentesis may reveal fetal anemia due to Rh sensitization in rare cases, it is not the primary test used for diagnosing Rh incompatibility. Blood antibody screening and Doppler assessment of the middle cerebral artery are preferred for Rh-related concerns.
D. Fetal breathing movements: Fetal breathing is assessed through a biophysical profile or real-time ultrasound, not via amniotic fluid sampling. Amniocentesis does not provide information about the fetus’s respiratory activity or movement patterns.

Correct Answer is B
Explanation
Rationale:
A. The client needs strict measurement of intake and output: This task can be delegated to assistive personnel as it involves routine data collection without complex clinical judgment.
B. The client develops a postoperative fever: A postoperative fever may indicate infection or other complications requiring assessment, clinical judgment, and intervention by a registered nurse.
C. The client is experiencing a therapeutic effect from their treatment: Monitoring expected therapeutic effects is routine and can often be overseen by licensed practical nurses or assistive personnel, depending on policy.
D. The client needs routine wound care performed: Routine wound care is generally a delegated nursing task that does not require the advanced assessment or clinical decision-making of an RN unless complications arise.
Correct Answer is D
Explanation
Rationale:
A. "Give the client several choices of foods for meals.": Providing multiple options can overwhelm a client with dementia and increase confusion or frustration. It is better to offer one or two simple choices to support decision-making without causing cognitive overload.
B. "Avoid making eye contact with the client.": Avoiding eye contact can appear dismissive or impersonal. Maintaining gentle eye contact helps establish trust, enhances communication, and can be grounding for clients who are cognitively impaired.
C. "Increase environmental stimuli”: A stimulating environment can lead to agitation or disorientation in clients with dementia. These clients benefit from calm, predictable surroundings with reduced noise, clutter, and distractions to support cognitive clarity.
D. "Label the door to the bathroom with a symbol.": Using clear labels or symbols helps orient clients with dementia and reduces confusion. Visual cues support recognition and promote independence in navigating their environment, especially with essential tasks like toileting.
