The nurse practicing in a maternity setting recognizes that the postmature fetus is at risk due to:
- A. Excessive fetal weight
- B. Low blood sugar levels
- C. Depletion of subcutaneous fat
- D. Progressive placental insufficiency
Correct Answer: D
Rationale: A postmature or postterm pregnancy occurs when a pregnancy exceeds the typical term of 38 to 42 weeks. In this situation, the fetus is at risk due to progressive placental insufficiency. This occurs because the placenta loses its ability to function effectively after 42 weeks. The accumulation of calcium deposits in the placenta reduces blood perfusion, oxygen supply, and nutrient delivery to the fetus, leading to potential growth problems. Choices A, B, and C are incorrect because excessive fetal weight, low blood sugar levels, and depletion of subcutaneous fat are not the primary risks associated with postmature fetuses. The main concern lies in the compromised placental function and its impact on fetal well-being.

Which of these statements best describes the characteristics of an effective reward feedback system?
- A. Specific feedback is given as close to the event as possible
- B. Staff is given feedback in equal amounts over time
- C. Positive statements precede negative statements
- D. Performance goals should be higher than what is attainable
Correct Answer: A
Rationale: The correct answer is that specific feedback should be given as close to the event as possible in an effective reward feedback system. This is important because feedback is most useful when provided immediately. Giving feedback promptly reinforces positive behavior and helps in modifying problem behaviors. Providing feedback close to the event helps in ensuring that standards are clearly understood and can be met. Choices B, C, and D are incorrect because staff should not be given feedback in equal amounts over time, positive statements do not necessarily have to precede negative statements, and setting performance goals higher than what is attainable can lead to demotivation and decreased performance.
A toddler has recently been diagnosed with cerebral palsy. Which of the following information should the nurse provide to the parents? Select one that doesn't apply.
- A. Regular developmental screening is important to avoid secondary developmental delays.
- B. Cerebral palsy is caused by injury to the upper motor neurons and results in motor dysfunction, as well as possible ocular and speech difficulties.
- C. Developmental milestones may be slightly delayed but usually will require no additional intervention.
- D. Parent support groups are helpful for sharing strategies and managing health care issues.
Correct Answer: C
Rationale: The correct answer is 'Developmental milestones may be slightly delayed but usually will require no additional intervention.' This statement is incorrect as delayed developmental milestones in a child with cerebral palsy require interventions and constant follow-ups. Developmental monitoring is essential to track a child's growth and development over time. If any concerns are raised during monitoring, a developmental screening test should be conducted promptly to address any developmental delays or issues. Regular interventions, therapies, and support are crucial to optimize the child's development and well-being. Therefore, it is important for parents to be aware that additional interventions may be necessary to support their child's development.
A patient with peripheral vascular disease is receiving discharge instructions. Which of the following information should be included?
- A. Walk barefoot whenever possible.
- B. Use a heating pad to keep feet warm.
- C. Avoid crossing the legs.
- D. Use antibacterial ointment to treat skin lesions prone to infection.
Correct Answer: C
Rationale: Patients with peripheral vascular disease should be advised to avoid crossing their legs as this can impede blood flow. Peripheral vascular disease, also known as arteriosclerosis obliterans, is primarily caused by atherosclerosis. Atherosclerosis results in the gradual progression of arterial occlusion due to the formation of atheromas. Crossed legs can further restrict blood flow, exacerbating the condition. Walking barefoot should be discouraged to prevent potential injuries to the feet. Using a heating pad can lead to burns and should be avoided to prevent thermal injuries. While using antibacterial ointment for skin lesions may be beneficial, it is not the priority instruction for patients with peripheral vascular disease.
A 23-year-old patient in the 27th week of pregnancy has been hospitalized on complete bed rest for 6 days. She experiences sudden shortness of breath, accompanied by chest pain. Which of the following conditions is the most likely cause of her symptoms?
- A. Myocardial infarction due to a history of atherosclerosis.
- B. Pulmonary embolism due to deep vein thrombosis (DVT).
- C. Anxiety attacks due to worries about her baby's health.
- D. Congestive heart failure due to fluid overload.
Correct Answer: B
Rationale: In a hospitalized patient on prolonged bed rest, the most likely cause of sudden onset shortness of breath and chest pain is pulmonary embolism. Pregnancy and prolonged inactivity both increase the risk of clot formation in the deep veins of the legs, known as deep vein thrombosis (DVT). These clots can dislodge and travel to the lungs, causing a pulmonary embolism. Myocardial infarction (Choice A) is less likely in a young patient without a significant history of atherosclerosis. Anxiety attacks (Choice C) may present with similar symptoms but are less likely in this context. Congestive heart failure (Choice D) is less probable given the acute onset of symptoms and absence of typical signs like peripheral edema in this case.
Is it true that Hepatitis C virus (HCV) can be spread through hugging, sneezing, coughing, sharing eating utensils, and other forms of casual contact?
- A. True
- B. False
Correct Answer: B
Rationale: False. HCV is not spread through casual contact such as hugging, sneezing, or sharing eating utensils. The correct modes of transmission for HCV include direct contact with human blood through blood transfusions, improperly sterilized needles and syringes, needle sharing, or occasionally through sexual contact. Therefore, the statement is false, making 'False' the correct answer. Choices A, C, and D are incorrect as they do not accurately reflect the mode of transmission of HCV.
