Test Bank Pharmacology and the Nursing Process

Correct Answer: C

Rationale: The correct nursing diagnosis is C: Impaired skin integrity. This choice is correct because it directly addresses the bacterial infection in the left lower leg by focusing on the skin's condition. The patient's skin integrity is compromised due to the infection, making this nursing diagnosis appropriate. Choice A (Infection) is too broad and does not specify the impact on the skin. Choice B (Risk for infection) is incorrect because the patient already has a bacterial infection, so the risk has already manifested. Choice D (Staphylococcal leg infection) is too specific and does not address the broader issue of skin integrity. Therefore, the best choice is C as it accurately reflects the patient's current condition and guides appropriate nursing interventions to address the impaired skin integrity caused by the bacterial infection.

Correct Answer: A

Rationale: Rationale: - Salt tablets are used for mild deficits of serum sodium to help restore electrolyte balance. - Sodium is crucial for fluid balance, nerve function, and muscle contraction. - Severe deficits of serum magnesium, potassium, and calcium require specific electrolyte replacement therapy, not salt tablets. Summary: - Choice A is correct because salt tablets are used for mild deficits of serum sodium. - Choices B, C, and D are incorrect because they involve severe deficits of different electrolytes that require specific replacement therapy.

Correct Answer: B

Rationale: The correct answer is B because in a normal Rinne test, air conduction is heard longer than bone conduction in both ears. This is due to the fact that air conduction involves the transmission of sound waves through the external auditory canal, middle ear, and inner ear, which is more efficient than bone conduction where the sound waves are transmitted directly to the inner ear through the bones of the skull. Therefore, when the tuning fork is placed on the mastoid bone (bone conduction) and then moved next to the ear (air conduction), the sound should be heard longer through air conduction. Choice A is incorrect because normal auditory acuity does not necessarily mean equal perception in both ears. Choice C is incorrect as bone conduction should be heard shorter than air conduction in a normal Rinne test. Choice D is incorrect as the test does not determine which ear perceives sound better, but rather the difference in duration between air and bone conduction.

Correct Answer: B

Rationale: The correct answer is B: Respiratory acidosis. Aspirin can lead to respiratory acidosis due to its effect on the respiratory center in the brainstem. It causes hyperventilation, leading to respiratory alkalosis initially, followed by respiratory acidosis as compensation mechanism fails. Weight gain is not a typical adverse reaction of aspirin. Fine motor tremors are not associated with aspirin therapy. Bilateral hearing loss is a rare but serious side effect of aspirin overdose, not prolonged therapy.
