Correct Answer: D

Rationale: Topical corticosteroids are mainly used for their localized effects. When treating atopic dermatitis with a steroidal preparation, there is a risk of the site being vulnerable to invasion by organisms. Viruses like herpes simplex or varicella zoster pose a threat of disseminated infection. Therefore, viral infection is a contraindication for topical corticosteroid use in clients with atopic dermatitis. It is crucial to educate clients using topical corticosteroids to avoid crowds or people with infections and to promptly report any signs of infection. Choices A, B, and C (parasitic, fungal, and spirochetal infections) are not typically contraindications for topical corticosteroid use in the context of atopic dermatitis, as these agents do not pose the same risk of disseminated infection or systemic effects as viral infections.

Correct Answer: D

Rationale: The use of clichés in therapeutic communication is commonly construed by the client as the nurse's lack of understanding, involvement, and caring, which can lead the client to feel demeaned and discounted. Choice A is incorrect because clichés do not make the client view the nurse as less understanding but rather as lacking depth in communication. Choice B is incorrect as clichés do not directly lead the client to accepting themselves as human. Choice C is incorrect because clichés usually hinder self-disclosure rather than encourage it.

Correct Answer: C

Rationale: The correct answer is 'relaxation technique.' Biofeedback techniques are a form of relaxation technique that can help individuals quiet the mind, release tension, and counteract responses to stress. Teaching biofeedback techniques to the client aims to promote relaxation and stress management. Choice A, 'structure,' does not directly relate to teaching biofeedback techniques. Choice C, 'time management,' focuses on organizing tasks efficiently, not on relaxation techniques. Choice D, 'regular exercise,' although beneficial for overall health, is not specifically related to the teaching of biofeedback techniques for stress relief.

Correct Answer: D

Rationale: Quinidine can cause widened Q-T intervals and heart block, leading to a prolonged QT interval on the ECG. Other signs of myocardial toxicity associated with quinidine include notched P waves and widened QRS complexes. Common side effects of quinidine include diarrhea, nausea, and vomiting, while less common effects may include tinnitus, vertigo, headache, visual disturbances, and confusion. Monitoring for a prolonged QT interval is crucial due to the potential risk of serious arrhythmias. Choices A, B, and C are not typically associated with the use of quinidine and are therefore incorrect in this context.

Correct Answer: B

Rationale: The correct answer is Protamine sulfate. Protamine sulfate is the antidote for heparin, as it reverses its effects. Cyanocobalamin is a form of Vitamin B12 and is not used to reverse heparin effects. Streptokinase is a thrombolytic agent that is used to dissolve blood clots, not to reverse heparin effects. Sodium warfarin is an anticoagulant, but it is not the antidote for heparin. Therefore, answers A, C, and D are incorrect as they do not reverse the effects of heparin.
