A 16-month-old child has just been admitted to the hospital. As the nurse assigned to this child enters the hospital room for the first time, the toddler runs to the mother, clings to her, and begins to cry. What would be the initial action by the nurse?

Correct Answer: B

Rationale: The correct answer is to explain that this behavior is expected. At 16 months of age, children commonly experience separation anxiety, especially in unfamiliar environments like hospitals. It is important for the nurse to reassure the child and the parent that such behavior is normal. Option A is incorrect as there is no need to change client care assignments based on the child's behavior. Option C is not appropriate as discussing the use of 'time-out' is more relevant in behavior management for older children. Option D is incorrect as it does not address the underlying cause of the child's behavior related to separation anxiety.

Correct Answer: A

Rationale: The correct action for a client with acute hypocalcemia is to implement seizure precautions. Hypocalcemia can lead to tetany and seizures due to neuromuscular irritability. Assessing for hypoglycemia (choice B) is not directly related to hypocalcemia. Monitoring for visual changes (choice C) is more indicative of conditions like hyperglycemia or retinal disorders. Observing for muscle weakness (choice D) is a common symptom of hypocalcemia but does not address the immediate risk of seizures, which is why implementing seizure precautions is the priority nursing action.

Correct Answer: D

Rationale: The correct answer is D: Bradycardia. Pyridostigmine, a cholinesterase inhibitor used in myasthenia gravis, can lead to bradycardia as a side effect. Choice A, constipation, is not a common side effect of pyridostigmine. Choice B, hypertension, is unlikely as pyridostigmine is more likely to cause hypotension. Choice C, muscle weakness, is actually a symptom of myasthenia gravis itself and not a side effect of pyridostigmine.

Correct Answer: A

Rationale: The correct answer is A: Prothrombin time (PT). Prothrombin time is monitored to assess the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors, including factors II, VII, IX, and X. Monitoring the PT helps ensure that the client's blood is clotting within the desired therapeutic range to prevent complications such as recurrent DVT or excessive bleeding. Choices B, C, and D are incorrect because serum potassium, blood urea nitrogen, and white blood cell count are not directly related to monitoring warfarin therapy in a client with a history of DVT.

Correct Answer: C

Rationale: The correct answer is C: Diarrhea. Ranitidine, which is used to treat peptic ulcer disease, can lead to gastrointestinal disturbances such as diarrhea. Choices A, B, and D are incorrect. Hypertension and hypotension are not common side effects of ranitidine. Constipation is also not a typical side effect associated with ranitidine use.
