Mortality of Hyperkalemia and Hypokalemia

Answer: d- Hypokalemia and Hyperkalemia both are associated with an increased risk of mortality.

Hyperkalemia and hypokalemia both are associated with increased risk of mortality, bit in patients with chronic kidney disease hyperkalemia spikes more often, so hyperkalemia is needed to be treated and corrected whereas hypokalemia is considered negligible.

Potassium Restricted Patients

Answer: a- The use of salt substitutes when cooking.

Salt substitutes are to be avoided as they contain Potassium. Fresh fruits and vegetables are preferred over canned ones. The canned fruits and vegetables can only be used if they are properly washed after opening. The vegetables rich in Potassium such as potatoes, carrots and winter squash can be consumed by leaching them. Leaching is the process of proper peeling, slicing and soaking the vegetable for two hours prior to cooking. Olive oil must be consumed over butter and fats, if butter is consumed the preferred is the unsalted one rather than the salted one.

Potassium Binders In CKD

Answer: a- A low Potassium diet should be maintained.

The use of newer Potassium binders such as Patirometer and Sodium Zirconium Cyclosilicate (SZC) should be taken with low potassium diet in chronic kidney disease patients. The Potassium binders must be taken as prescribed without abrupt stopping due to rebound effects. A normal single Potassium diet causes spike in Potassium levels after one meal, so the implementation of Potassium restrictions on alternate days is not recommended.

Potassium Intake In Chronic Kidney Disease

Answer: c- ≤2-3g/ day

Salt intake should be limited to 2000mg/ day which is equivalent to 1 teaspoon a day and Potassium intake should be limit to ≤2-3g/ day depending on the stage of chronic kidney disease.

Immunity to Measles

Answer: a- Documentation of at least 1 MMR Vaccine.

Pregnant women who are exposed to measles or suspected for measles are supposed to get 1 MMR vaccine for average risk and 2 MMR doses for high risk patients. A positive ELISA test suggests immunity to measles and in those cases PRNT is not needed to be conducted.

Measles Transmission

Answer: b- Persons are considered infectious from day four before the onset to rash to four days after the appearance of rash.

Measles have an incubation period of 7 to 21 days, but persons are infectious at day 4 before the onset of rash to four days after the appearance of rash, and the measles virus is airborne and infectious for 2 hours. The two doses of MMR vaccine are sufficient to provide immunity of around 97%, about 92%-95% of the population must be vaccinated for measles virus in order to prevent ongoing transmission.
