During an examination, the nurse can assess mental status by which activity?

Correct Answer: C

Rationale: In a health assessment, mental status evaluation is crucial for understanding a patient's overall well-being. Option C, observing the patient and inferring health or dysfunction, is the correct activity for assessing mental status during an examination. This is because observing the patient's behavior, speech, and overall demeanor can provide valuable insights into their mental functioning, emotional state, and cognitive abilities. It allows the nurse to assess for signs of alertness, orientation, memory, mood, and thought processes, which are essential components of mental status evaluation. Examining the patient's electroencephalogram (Option A) is not typically used to assess mental status during a routine examination. An EEG is a test that measures electrical activity in the brain and is primarily used to diagnose conditions like seizures or sleep disorders. Observing the patient as they perform an IQ test (Option B) is more focused on assessing cognitive abilities rather than overall mental status. While IQ tests provide information about a person's intellectual functioning, they do not capture the full spectrum of mental status evaluation, including emotional and behavioral aspects. Examining the patient's response to a specific set of questions (Option D) is a component of assessing mental status, particularly cognitive functions like attention, memory, and comprehension. However, relying solely on a set of questions may not provide a comprehensive understanding of the patient's mental status as it may miss non-verbal cues and behavioral indicators that are crucial in mental health assessment. In an educational context, understanding the correct method for assessing mental status is essential for nurses and healthcare professionals to provide holistic care. By honing observational skills and learning how to interpret behavioral cues, nurses can gather valuable information about a patient's mental well-being, leading to more accurate assessments and tailored interventions.

Correct Answer: A

Rationale: The correct response, option A, "You're afraid you might lose your breast?" is the most therapeutic because it demonstrates active listening and empathy towards the patient's emotional state. By reflecting the patient's feelings back to her, the nurse shows understanding and opens up a supportive dialogue, allowing the patient to express her fears and concerns. Option B, "No, I'm not sure what you are talking about," is dismissive and invalidating of the patient's emotions, which can worsen the patient's distress. This response lacks empathy and fails to address the patient's immediate emotional needs. Option C, "I'll wait here until you get yourself under control, and then we can talk," is insensitive and implies impatience. It disregards the patient's current emotional state and fails to offer immediate support or comfort. Option D, "I can see that you are very upset. Perhaps we should discuss this later," is also not as therapeutic as option A. It postpones the conversation and does not actively engage with the patient's feelings in the moment, missing an opportunity to provide immediate emotional support and connection. In an educational context, this scenario highlights the importance of therapeutic communication skills in nursing practice. Active listening, empathy, and validation of patient emotions are crucial in establishing trust and rapport with patients, especially in sensitive situations like delivering a cancer diagnosis. Nurses must prioritize patient-centered care and emotional support to effectively meet the holistic needs of patients.

Correct Answer: C

Rationale: The best way to begin assessing a 2-year-old child is by allowing the child to keep a toy or blanket for comfort, which is option C. This approach is rooted in child development principles and pediatric nursing best practices. Children at this age can be fearful or anxious in unfamiliar environments, so providing them with a familiar object like a toy or blanket can help establish trust and create a sense of security during the assessment. This can help the child feel more comfortable and cooperative, leading to a more accurate assessment of their vital signs. Option A, asking the parent to place the child on the exam table, may cause distress to the child by separating them from the parent and can lead to resistance during the assessment. Option B, having the child remove all clothing before the exam, may be overwhelming and invasive for a young child, potentially leading to increased anxiety and resistance. Option D, directly interacting with the child and ignoring the parent, is not recommended as young children often rely on their parents for security and comfort, especially in unfamiliar situations. In pediatric nursing, it is essential to involve parents in the care of their children and to prioritize the child's emotional well-being during assessments. In conclusion, allowing the child to keep a toy or blanket for comfort is the most appropriate way to begin assessing a 2-year-old child as it promotes a sense of security, comfort, and cooperation, ultimately facilitating a successful health assessment.

Correct Answer: B

Rationale: In this scenario, option B, "Consider these findings normal for a 1-month-old infant," is the correct choice. During infancy, it is typical for an infant's head circumference to be larger than their chest circumference. These measurements fall within the expected range for a 1-month-old infant and do not raise any immediate concerns regarding growth or development. Option A, "Refer the infant to a physician for further evaluation," is incorrect as there are no alarming signs in the provided measurements that would warrant an immediate referral to a physician. Option C, "Expect the chest circumference to be greater than the head circumference," is incorrect as it goes against typical infant growth patterns where the head circumference is usually larger in proportion to the chest circumference. Option D, "Ask the parent to return in 2 weeks to re-evaluate the head and chest circumferences," is unnecessary in this case as the measurements are within the normal range for a 1-month-old infant and do not require immediate reassessment. Educationally, understanding normal variations in infant growth parameters is crucial for healthcare providers to appropriately assess and monitor infant development. It is essential to recognize what is considered normal versus abnormal to provide appropriate care and avoid unnecessary referrals or interventions.

Correct Answer: D

Rationale: In the context of measuring blood pressure, the correct answer is D) Peripheral vascular resistance. This is because blood pressure is determined by the resistance the blood encounters as it flows through the blood vessels. Peripheral vascular resistance refers to the resistance offered by the small arteries throughout the body. When these arteries constrict, the resistance increases, leading to higher blood pressure. Option A) Pulse rate is incorrect because while pulse rate is related to cardiovascular health, it specifically refers to the number of times the heart beats per minute and not directly to blood pressure. Option B) Pulse pressure is the difference between the systolic and diastolic blood pressure readings. While pulse pressure is an important indicator of cardiovascular health, it is not a factor that directly determines blood pressure. Option C) Vascular output is not a direct factor in determining blood pressure. Vascular output refers to the amount of blood pumped by the heart in a minute and is more related to cardiac output than blood pressure. Understanding the factors that influence blood pressure is crucial for healthcare professionals to accurately assess a patient's cardiovascular health. Knowledge of peripheral vascular resistance helps nurses and other healthcare providers in interpreting blood pressure readings, identifying abnormalities, and making informed decisions regarding patient care and interventions.
