A nurse is preparing to assess the fetal heart rate (FHR) of a client who is 14 weeks pregnant. Which piece of equipment does the nurse use to assess the FHR?

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: D

Rationale: The correct answer is that the young adult verbalizes satisfaction with friendships. Emotional health in young adults is characterized by various positive signs, including satisfaction with social interactions and friendships. Expressing contentment with friendships indicates a healthy emotional state, fostering positive social connections. On the other hand, sensitivity to criticism, verbalizing unrealistic fears, and expressing disappointment with life are all indicative of emotional distress and potential mental health challenges. These behaviors can hinder social relationships and overall emotional well-being.

Correct Answer: D

Rationale: The correct action in this scenario is to call the surgical area and explain that the surgery will have to be cancelled. The client must sign the operative permit or any other legal document before receiving preoperative medication. Without the signed permit, the surgery cannot proceed to ensure the client's safety and legal compliance. Having the client sign the permit, witnessing the form after the client signs it, or having someone else sign the form are all inappropriate actions and do not address the legal requirement of the client's signature before receiving preoperative medication.

Correct Answer: C

Rationale: For a 2-year-old child, saying 'Mine!' when playing with toys is an example of age-appropriate play. Toddlers at this age are possessive and asserting their sense of ownership. Building towers with blocks and trying to color within the lines involve more advanced motor skills and cognitive abilities that are typically not fully developed in a 2-year-old. Jumping rope requires coordination and balance beyond what a 2-year-old can usually achieve. Therefore, choices A, B, and D are not considered age-appropriate plays for a 2-year-old child.

Correct Answer: C

Rationale: The correct answer is 'Decreased older client's ability to clear secretions.' Respiratory changes related to the normal aging process decrease an older adult's ability to clear secretions and protect the airway. In healthy older adults, the number of alveoli does not change significantly; their structure, however, is altered. Respiratory system compliance decreases with advancing age because of a progressive loss of elastic recoil of the lung parenchyma and conducting airways, and reduced elastic recoil of the lung and opposing forces of the chest wall. Production of surfactant in the lung does not usually decrease with aging, nor does it increase. However, the production of alveolar cells responsible for surfactant production is diminished. Choices A, B, and D are incorrect. Choice A is incorrect because respiratory system compliance decreases with aging. Choice B is incorrect as the number of alveoli does not significantly decrease in healthy older adults. Choice D is incorrect as the production of surfactant does not usually decrease with aging.

Correct Answer: B

Rationale: The correct answer is B: secondary prevention. The client is currently receiving secondary prevention care. Secondary prevention focuses on early detection of disease, prompt intervention, and health maintenance for clients experiencing health problems. In this case, the electrolyte imbalance is a health problem that requires treatment to prevent further complications. Choices A, C, and D are incorrect because primary prevention is focused on health promotion and specific protections against illness before it occurs, tertiary prevention is aimed at helping rehabilitate clients after the illness is diagnosed and treated, and health promotion is a broader concept that includes activities aimed at improving overall health and well-being rather than targeting a specific health problem like an electrolyte imbalance.

Correct Answer: A

Rationale: School-age children are capable of taking responsibility for their own dental hygiene. Establishing good oral health habits during childhood can lead to a lifetime of cavity prevention. The nurse advises the parents that their children should brush with fluoride toothpaste and floss between their teeth after meals and before bedtime. This routine helps maintain good oral health and teaches children the importance of dental care. Choice A is the correct answer as it emphasizes both brushing and flossing after meals and at bedtime, which are crucial for effective dental care. Choices B, C, and D are incorrect as they do not stress the significance of both brushing and flossing after meals, which is essential for proper oral hygiene.

Correct Answer: D

Rationale: The tissue that would receive the highest amount of cardiac output and thus the highest amount of a drug is the myocardium. Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being part of the heart, receives a significant amount of cardiac output. Choices A (skin) and B (adipose tissue) are poorly perfused tissues and would not receive high amounts of cardiac output. Choice C (skeletal muscle) is also less perfused compared to the myocardium.

Correct Answer: D

Rationale: The correct answer is medication instruction. This is a skilled service that requires specialized knowledge and training to provide proper guidance on medication management for a client with type I diabetes. Grocery shopping, house cleaning, and transportation services are considered unskilled services as they are typically offered by volunteer or fee-for-service agencies and do not require specialized medical expertise. Medication instruction, on the other hand, involves educating the client on how to properly take medications, understand potential side effects, and manage their medication regimen effectively, which necessitates a high level of expertise and training.
