The nurse is planning care for a client with pneumococcal pneumonia. Which of the following would be most effective in removing respiratory secretions?

Correct Answer: B

Rationale: Increasing oral fluid intake to 3000 cc per day is the most effective in removing respiratory secretions in a client with pneumococcal pneumonia. Adequate hydration helps thin secretions, making them easier to expectorate. Administration of cough suppressants (Choice A) may hinder the removal of secretions by suppressing the cough reflex. Maintaining bed rest with bathroom privileges (Choice C) is important but does not directly address the removal of respiratory secretions. Performing chest physiotherapy (Choice D) is beneficial for mobilizing secretions but may not be as effective as increasing fluid intake in thinning and facilitating the removal of secretions.

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.

Correct Answer: B

Rationale: The correct answer is B because the statement "I'd rather not talk about it right now" indicates that the client is consciously choosing to avoid discussing the distressing issue, which aligns with the mechanism of suppression. Choice A does not involve active avoidance but rather memory loss, which is not suppression. Choice C involves blaming others, which is a defense mechanism known as projection. Choice D involves expressing emotions rather than avoiding them, which does not align with suppression.
