A patient with a potassium level of 2.8 mEq/L is given 60 mEq over a 12-hour period, and a repeat potassium level is obtained after the bolus. The current potassium level is 2.9 mEq/L. Which of the following should now be considered?
 
  a. Stopping the patient's Aldactone
  b. Drawing a serum magnesium level
  c. Rechecking the potassium level
  d. Monitoring the patient's urinary output

Question 2

Answer to Question 1

B
A total serum magnesium concentration below 1.5 mEq/L defines hypomagnesemia. It is commonly associated with other electrolyte imbalances, most notably alterations in potassium, calcium, and phosphorus. Low serum magnesium levels can result from many causes.

Answer to Question 2

C
Pathogens that can cause health careassociated pneumonia are similar to those causing both community- and hospital-acquired pneumonia (HAP) with Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus (MRSA) being the most common in the United States. Pathogens that can cause HAP include Escherichia coli, Haemophilus influenzae, methicillin-sensitive Staphylococcus aureus, Streptococcus pneumoniae, P. aeruginosa, Acinetobacter baumannii, MRSA, Klebsiella spp., and Enterobacter spp.
