Theories of Health Behavior Change Questions
Question 1 of 5
Nurse John is caring for a male client receiving lidocaine I.V. Which factor is the most relevant to administration of this medication?
Correct Answer: C
Rationale: The correct answer is C: Presence of premature ventricular contractions (PVCs) on a cardiac monitor. Lidocaine is commonly used to treat PVCs and ventricular arrhythmias. Monitoring for PVCs is crucial to assess the effectiveness of the medication. A decrease in arterial oxygen saturation (A) is not directly related to lidocaine administration. An increase in systemic blood pressure (B) is not a primary concern with lidocaine. Increase in intracranial pressure (ICP) (D) is not directly affected by lidocaine administration.
Question 2 of 5
When performing oral care on a comatose client, Nurse Krina should:
Correct Answer: C
Rationale: Rationale for Choice C: 1. Placing the client in a side-lying position prevents aspiration. 2. Lowering the head of the bed helps with drainage and reduces the risk of choking. 3. This position also allows for better access to perform oral care safely. Summary of other choices: A. Applying lemon glycerin frequently can be drying and irritating to the lips. B. Brushing teeth with the client lying supine can increase the risk of aspiration. D. Cleaning the client's mouth with hydrogen peroxide can be harmful if ingested and is not recommended for routine oral care.
Question 3 of 5
Diagnostic assessment of Francis would probably not reveal:
Correct Answer: D
Rationale: The correct answer is D: Elevated thrombocyte counts. Diagnostic assessment of Francis, who likely has leukemia, would not reveal elevated thrombocyte counts because leukemia typically causes thrombocytopenia, not thrombocytosis. Thrombocytosis is an increased platelet count, which is not a common feature of leukemia. Predominance of lymphoblasts, leukocytosis, and abnormal blast cells in the bone marrow are all characteristic findings in leukemia.
Question 4 of 5
Antonio with lung cancer develops Horner's syndrome when the tumor invades the ribs and affects the sympathetic nerve ganglia. When assessing for signs and symptoms of this syndrome, the nurse should note:
Correct Answer: A
Rationale: The correct answer is A: miosis, partial eyelid ptosis, and anhidrosis on the affected side of the face. Horner's syndrome results from disruption of sympathetic nerve pathway, leading to these specific symptoms. Miosis (constricted pupil) occurs due to unopposed parasympathetic activity, partial eyelid ptosis (drooping eyelid) due to loss of sympathetic innervation to the eyelid muscle, and anhidrosis (lack of sweating) due to loss of sympathetic innervation to sweat glands. These symptoms are classic in Horner's syndrome. Choice B is incorrect because the symptoms listed are more indicative of general symptoms of lung cancer rather than specific to Horner's syndrome. Choice C is incorrect as it describes symptoms related to brachial plexopathy, not Horner's syndrome. Choice D is incorrect as hoarseness and dysphagia are not typical symptoms of Horner's syndrome.
Question 5 of 5
Mr. Rodriguez is admitted with severe pain in the knees. Which form of arthritis is characterized by urate deposits and joint pain, usually in the feet and legs, and occurs primarily in men over age 30?
Correct Answer: D
Rationale: The correct answer is D: Gouty arthritis. This form of arthritis is characterized by urate deposits and joint pain, commonly in the feet and legs. Gout primarily affects men over age 30. Urate crystals form due to high levels of uric acid in the blood, leading to inflammation and pain in the joints. Septic arthritis (A) is caused by an infection in the joint, traumatic arthritis (B) results from joint injury, and intermittent arthritis (C) is not a recognized medical term.
