Correct Answer: D

Rationale: The correct placement for auscultating the apical heart rate in the area of the mitral valve is the fifth left interspace at the midclavicular line. Placing the stethoscope in the second left interspace would be to listen to the pulmonic valve, the second right interspace is for the aortic valve, and the left lower sternal border is for the tricuspid valve.

Correct Answer: B

Rationale: The correct answer is '6 months.' At around this age, children typically start to develop 'stranger anxiety' as they become more aware of unfamiliar faces and may start showing signs of distress or anxiety around strangers. At 3 months, infants are still very young and unlikely to display stranger anxiety. While by 9 or 12 months, children have usually already developed some level of stranger anxiety, it typically starts around 6 months, making it the most appropriate answer in this context.

Correct Answer: D

Rationale: Providing perineal care is not the least appropriate when caring for a stable postpartum client. Perineal care is essential for maintaining hygiene and preventing infection after delivery. Assessing the location and height of the fundus helps in monitoring postpartum uterine involution, which is crucial for assessing the recovery progress. Conducting a family assessment, including the mother's future plans for returning to work, is important for understanding the support system available for the mother during the postpartum period. Monitoring the client for bleeding is critical to promptly identify and address any postpartum hemorrhage. Therefore, providing perineal care is the least appropriate option among the choices provided as it is a fundamental aspect of postpartum care.

Correct Answer: C

Rationale: The nurse is documenting an abnormal bronchophony assessment finding. Bronchophony is a technique where the nurse asks the client to repeat a specific word, such as 'ninety-nine,' while listening through the stethoscope. Normally, the voice transmission is soft, muffled, and indistinct. However, if there is a pathologic condition increasing lung density, the nurse will hear the word clearly, indicating an abnormality. Vesicular breath sounds are normal sounds heard over peripheral lung fields and are not related to vocal resonance assessment. Egophony involves the client phonating a long 'ee-ee-ee-ee' sound, not repeating a specific word. Whispered pectoriloquy involves whispering a phrase like 'one-two-three,' not repeating a specific word. In these cases, normal findings are 'eeeeee' for egophony and a muffled, almost inaudible sound for whispered pectoriloquy.

Correct Answer: A

Rationale: Primary prevention involves activities that promote wellness or prevent illness or injury. Educating parents about safety measures in the home aims to prevent injuries, making it a primary prevention strategy. Secondary prevention focuses on early detection and intervention in diseases or injuries. Tertiary prevention involves reducing disability and promoting optimal functioning in relation to a disease or injury. Health promotion encompasses activities that enhance a client's overall health and well-being. In this scenario, educating parents about safety in the home falls under primary prevention as it aims to prevent injuries before they occur.
