What location would the nurse assess for a pedal pulse?

Back of the knee

The bend of the arm

The neck

Top of the foot

Answer and Explanation

The Correct Answer is D

A. Back of the knee: The back of the knee is where the popliteal pulse is located, not the pedal pulse. The popliteal pulse is assessed behind the knee and is not related to the foot or pedal area.

B. The bend of the arm: The pulse at the bend of the arm is the brachial pulse, which is located at the elbow. This is unrelated to the pedal pulse, which is found at the foot.

C. The neck: The neck contains the carotid pulse, which is assessed by palpating the carotid artery on either side of the neck. This location is unrelated to the pedal pulse, which is specifically assessed at the foot.

D. Top of the foot: The pedal pulse is located on the top of the foot, near the area where the foot meets the ankle. This pulse is typically checked to assess circulation to the lower extremities and is important for evaluating peripheral vascular health.

Correct Answer is B

Explanation

A. Optic function: While potassium plays a role in cellular processes, including those in the eyes, its primary effects are felt in areas like the cardiovascular system. The optic nerve and visual processing are not influenced by potassium levels.

B. Cardiac function: Potassium is crucial for maintaining normal cardiac function. It helps regulate the electrical activity of the heart, and its imbalance can lead to arrhythmias, which can be life-threatening. Hypokalemia can cause disturbances in the heart’s rhythm, making it the most critical aspect to address.

C. Auditory function: Potassium levels do not affect auditory function. Potassium is involved in bodily functions, including maintaining the electrochemical gradients necessary for nerve and muscle activity, but it does not have a role in hearing or auditory processes.

D. Skeletal function: Potassium is important for muscle function, including skeletal muscles. Potassium’s role in muscle contraction extends to both skeletal and smooth muscles, but its impact on the heart’s electrical system makes cardiac function the priority.

A. The assistive personnel holds sterile objects above the waist level B. The assistive personnel handles the catheter with sterile gloves C. The assistive personnel opens the sterile package towards them D. The assistive personnel avoids talking over the sterile field

Correct Answer is C

Explanation

A. The assistive personnel holds sterile objects above the waist level: This is correct sterile technique because holding objects above waist level helps maintain sterility by preventing contamination from below or the patient’s environment.

B. The assistive personnel handles the catheter with sterile gloves: Using sterile gloves to handle the catheter is essential to prevent introducing pathogens and maintain a sterile field.

C. The assistive personnel opens the sterile package towards them: Opening a sterile package towards oneself increases the risk of contaminating the sterile contents by accidentally touching or breathing on them. The correct technique is to open the package away from the body.

D. The assistive personnel avoids talking over the sterile field: Avoiding talking over the sterile field prevents contamination from respiratory droplets and is an important infection control measure.
