Correct Answer: B

Rationale: The correct answer is B: The diaphragm of the stethoscope. The diaphragm is used to assess heart murmurs as it allows for higher-frequency sounds to be heard more clearly. When assessing heart murmurs, using the diaphragm helps to differentiate between systolic and diastolic murmurs, as well as to identify specific characteristics such as intensity and location. A: The bell of the stethoscope is used for low-frequency sounds and would not be ideal for assessing heart murmurs. C: Palpation with the palm of the hand is used to assess pulses and vibrations, not heart murmurs. D: Asking another nurse to double-check the finding is important for validation but does not directly relate to the technique used to assess a heart murmur.

Correct Answer: C

Rationale: The correct answer is C: Monitoring for signs of hemorrhage. This is the priority intervention because post-cesarean section hemorrhage is a life-threatening complication that requires immediate attention. The nurse should monitor the patient's vital signs, uterine firmness, and amount of vaginal bleeding to detect any signs of hemorrhage and take prompt action if necessary. Option A is incorrect because pain management is important but not the priority in this situation. Option B is also incorrect as breastfeeding can be encouraged after the patient's condition is stable. Option D is not the priority as preventing deep vein thrombosis is important but not as urgent as monitoring for hemorrhage.

Correct Answer: A

Rationale: The correct answer is A: "Do you use sunscreen while outside?" because it directly relates to health promotion by addressing preventive measures. Sunscreen helps prevent skin cancer and other skin conditions. Choice B is incorrect as it focuses on assessing skin condition rather than promoting health. Choice C is incorrect as it relates to symptoms rather than prevention. Choice D is incorrect as it is related to assessing a specific symptom rather than promoting overall health.

Correct Answer: C

Rationale: The correct answer is C: "I should smoke to relieve stress and manage symptoms." This statement indicates a need for further education because smoking can worsen asthma symptoms. Here's the rationale: 1. Smoking is a common trigger for asthma exacerbations due to irritants in tobacco smoke. 2. Smoking can lead to airway inflammation and constriction, making asthma symptoms more severe. 3. Asthma management involves avoiding smoking and secondhand smoke exposure. 4. Choices A, B, and D are correct as they align with asthma management guidelines to avoid triggers and use inhalers as prescribed.
