✍️ Sample PCT Questions & Answers
1. The correct cuff size for measuring blood pressure is determined by:
The cuff bladder must encircle approximately 80% of the upper arm circumference for accurate readings—too small reads high, too large reads low.
2. A PCT enters a patient's room and finds them on the floor. What is the first action the PCT should take?
The first priority after a patient fall is to assess the patient for any injuries and check their vital signs. Before moving the patient, it is crucial to determine their condition to prevent further harm. Calling for help from a nurse is the immediate next step after the initial assessment.
3. A patient's oxygen saturation (SpO2) reading of 88% indicates:
An SpO2 of 88% is below the normal threshold of 95% and indicates significant hypoxemia requiring immediate nursing notification.
4. When instructing a female patient on how to collect a clean-catch midstream urine specimen, the PCT should tell her to:
A clean-catch midstream specimen requires careful technique to prevent contamination. The patient should first clean the perineal area, then begin urinating into the toilet, stop the stream, collect the specimen in the cup, and finally finish urinating in the toilet. This ensures the sample is from the middle of the urine stream, which is least likely to be contaminated.
5. What is the purpose of applying sterile dressings to surgical wounds?
Sterile dressings act as a physical barrier, shielding the surgical wound from external contaminants like bacteria and dirt. They also absorb exudate, maintain a moist healing environment, and reduce the risk of infection, which is vital for proper wound closure and recovery. Their purpose is not decorative or to prevent scarring, but rather protective and preventative.
6. Which device delivers low-flow oxygen to patients?
A nasal cannula is a common, comfortable device used to deliver low concentrations of oxygen, typically for patients requiring 1-6 liters per minute. It consists of two prongs that fit into the nostrils, making it suitable for patients who can breathe on their own but need supplemental oxygen. Other options like ventilators and CPAP machines deliver higher flows or positive pressure, while a nebulizer delivers medication.
