Correct Answer: A

Rationale: The toddler's behavior of asserting possession ('Mine') reflects a desire for independence, aligning with Erikson's stage of Autonomy vs. Shame and Doubt. This stage, typical for toddlers aged 1-3 years, focuses on developing a sense of control and independence. Choices B, C, and D are incorrect: Industry vs. Inferiority relates to middle childhood, Initiative vs. Guilt pertains to preschoolers, and Trust vs. Mistrust is associated with infancy.

Correct Answer: D

Rationale: The correct answer is D because informing about state law emphasizes the legal requirement and public health rationale behind prophylactic eye treatment to prevent serious infections like gonorrheal or chlamydial ophthalmic infection. Choices A, B, and C are incorrect. Choice A focuses on staphylococcus infection, which is not the primary concern addressed by the prophylactic ointment. Choice B mentions a specific infection acquired from the mother's infected vagina, which is not the main reason for the ophthalmic ointment. Choice C discusses tear duct obstruction and dry eyes, which are not the primary concerns addressed by the prophylactic ointment.

Correct Answer: B

Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy. Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.

Correct Answer: C

Rationale: The correct answer is C: 'Gradual onset of dyspnea.' While pulmonary embolism can present with various symptoms, the most common include sudden onset of dyspnea, chest pain (often pleuritic in nature), tachypnea, and tachycardia. Bilateral leg swelling is more commonly associated with conditions like deep vein thrombosis, not pulmonary embolism. Decreased breath sounds on auscultation may be seen in conditions like pneumothorax, not typically in pulmonary embolism. Therefore, the gradual onset of dyspnea is the most indicative symptom of pulmonary embolism in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Heart rate. Before administering digoxin to a client with a history of congestive heart failure, the nurse must assess the client's heart rate. Digoxin can cause bradycardia, so monitoring the heart rate is crucial to prevent potential complications. Assessing blood pressure, respiratory rate, and oxygen saturation are important assessments but are not as directly influenced by digoxin as heart rate is in this scenario. Blood pressure can be affected by various factors, including dehydration or other medications. Respiratory rate and oxygen saturation are more related to respiratory function and gas exchange, which are not the primary concerns when administering digoxin to a client with heart failure.
