Answer:

You would NOT include avocados in a renal healthy diet as they are high in potassium and can lead to further kidney damage and electrolyte abnormalities, since the kidneys cannot adequately filter out the excess.

Question:

Mrs. Jones is a 77 year old female patient. She presents today with complaints of "dizziness" and "feeling drained". She explains to you (the nurse) that her routine has remained the same for the previous six months, she can't understand what could be causing her to feel this way. You obtain vital signs on this patient; you notice the following VS: BP: 121/78 Pulse: 34 bpm Respirations: 16 Temp: 98.5 F Pulse Ox 93% on room air You notice that Mrs. Jones has a low heart rate/pulse and you understand that having a heart rate below 55 bpm may cause fatigue and dizziness. As you review Mrs. Jones home medication list you see the following medications: A. Lasix 10 mg PO once daily B. Sertraline 50 mg PO once daily C. Metoprolol 50 mg PO once daily D. Pantoprazole 40 mg PO daily Which medication do you anticipate being the cause of Mrs. Jones bradycardia (heart rate less than 60 bpm) and consequently possibly being the cause of her fatigue and dizziness?

Answer:

C. Metoprolol 50 mg PO once daily. This medication is a beta-adrenergic blocking agent. Meaning it blocks beta 1 receptor stimulation in the heart--resulting in a lower blood pressure but specifically a lower heart rate. This is a common antihypertensive medication and rate control medication of rapid heart rates in patients with conditions like atrial fib. Perhaps the nurse could make the provider aware and the dosage could be lowered--resulting in improvement in Mrs. Jones condition.

Answer:

D. Left Ventricle. As blood is pumped naturally through the heart, the final chamber that it reaches is the left ventricle; it is then immediately pushed out of the left ventricle and into systemic circulation.
