The client is taking a medication that digests the fibrin network in a blood clot. What medication is the client likely taking?

Correct Answer: B

Rationale: The correct answer is B: Streptokinase. Streptokinase is a thrombolytic medication that works by activating plasminogen to convert into plasmin, which then digests the fibrin network in a blood clot. Heparin (A) and Warfarin (C) are anticoagulants that prevent blood clots but do not directly digest fibrin. Ticlid (D) is an antiplatelet medication that inhibits platelet aggregation, not fibrin digestion.

Correct Answer: D

Rationale: The correct answer is D: Between the S2 and the S1 beat. A diastolic murmur is heard during the relaxing phase of the heart cycle, between the closure of the aortic valve (S2) and the mitral valve (S1) opening. This indicates a problem with the heart valves during diastole. Choices A, B, and C do not align with the timing of diastolic murmurs in the cardiac cycle and are therefore incorrect.

Correct Answer: C

Rationale: The correct answer is C: Type 1 second degree AV block. This rhythm is characterized by a slightly irregular rhythm and P waves that come in multiples, known as "grouped beating." In Type 1 AV block, there is a progressive lengthening of the PR interval until a QRS complex is dropped. This is consistent with the description provided in the question. A: Third degree AV block is characterized by complete dissociation between the atria and ventricles, resulting in an atrial rate that is typically faster than the ventricular rate. This is not the case in the scenario described. B: Type 2 second degree AV block is characterized by intermittent failure of conduction of P waves to the ventricles, resulting in dropped QRS complexes. This is not consistent with the description provided. D: Junctional escape rhythm is characterized by an escape rhythm originating from the AV junction, resulting in a heart rate of 40-60 bpm. This is not the rhythm described

Correct Answer: D

Rationale: The correct answer is D because the fact that the pain goes away after taking a nitroglycerin tablet is a classic characteristic of chronic stable angina. Nitroglycerin is a vasodilator that helps relieve angina by increasing blood flow to the heart. This response is specific to angina and indicates that the pain is likely due to coronary artery disease. A: "The pain wakes me up at night" is not specific to angina and could indicate other issues like gastroesophageal reflux disease. B: "The pain is level 3 to 5" is subjective and doesn't provide diagnostic value for angina. C: "The pain has gotten worse over the last week" may suggest a change in condition but doesn't confirm the diagnosis of chronic stable angina.

Correct Answer: B

Rationale: The correct answer is B: Heart rate increases from 66 to 98 beats/min. After an AMI, an increase in heart rate during ambulation may indicate cardiac strain or insufficient oxygen delivery. This suggests the exercise level should be decreased to prevent further cardiac stress. A: O saturation drops from 99% to 95% - This decrease in oxygen saturation can indicate impaired gas exchange but is not a direct indicator of cardiac strain during exercise. C: Respiratory rate goes from 14 to 20 breaths/min - An increase in respiratory rate may suggest increased effort but does not specifically indicate cardiac strain. D: Blood pressure (BP) changes from 118/60 to 126/68 mm Hg - This change in BP is within a normal range and does not directly signal a need to decrease exercise level.
