The nurse is caring for a patient whose blood type is A-. The nurse knows that this patient can receive the following blood types:(SELECT ALL THAT APPLY)
A-
АB
O-
A-
O+
Correct Answer : A,C,D
A. A patient with blood type A- can receive A- blood, as it matches both the ABO blood group and Rh factor.
B. A patient with A- blood cannot receive AB blood because the blood type is incompatible in terms of both ABO group and Rh factor. AB blood contains both A and B antigens, which could lead to an immune response in a type A patient.
C. O- blood is a universal donor for all blood types, meaning it does not contain A or B antigens and does not have the Rh factor, so it can be given to an A- patient.
D. As already noted, A- blood is compatible with an A- patient because both the ABO group and Rh factor are the same.
E. O+ blood contains the Rh antigen, and since the patient is A-, they cannot receive Rh-positive blood, as this could cause an immune reaction.

Correct Answer is D
Explanation
A. This would be concerning, but it is not the correct choice. If a pacemaker is functioning abnormally, it would require an assessment and troubleshooting, not simply a routine rhythm.
B. This is typical for biventricular pacemakers used in heart failure patients, but it would not apply to a patient with a standard pacemaker unless specified. A recent pacemaker placement does not necessarily indicate biventricular pacing.
C. This is correct if only the atrium is paced; however, in the case of a typical pacemaker like DDD (dual- chamber pacemaker), both the atrium and ventricle are paced.
D. This is correct for dual-chamber pacemakers (like DDD), which pace both the atrium and the ventricle to coordinate the heart's rhythm.
Correct Answer is D
Explanation
A. Carotid massage can be used as a vagal maneuver for certain types of supraventricular tachycardia (SVT), particularly in stable patients. However, it is not recommended in cases where the patient has a history of cocaine use or is showing signs of instability because of the potential for triggering a serious event, like a stroke.
B. Adenosine is a medication commonly used for the treatment of SVT. However, it should be given with caution and only after assessing the patient's condition. In this case, the patient needs to be assessed first, including vital signs, level of consciousness, and overall stability, before any medications are administered.
C. Electrical cardioversion is indicated for unstable SVT (e.g., signs of hemodynamic instability such as hypotension, chest pain, or altered mental status). However, this patient is only reporting a "racing heart" and nervousness and has not yet been assessed for vital signs or other clinical symptoms.
D. The first step in this case should be to assess the patient's condition. This includes checking the vital signs, level of consciousness, and overall stability. Once this initial assessment is performed, the nurse can then determine whether medications or other interventions (like adenosine or cardioversion) are needed.
