The deltoid injection site is located approximately 2 inches (2-3 finger widths) below the acromion process of the shoulder.

When obtaining a throat culture, the swab should be applied to which area?

Answer: The tonsillar pillars and posterior pharynx

The tonsillar pillars and posterior pharynx harbor the pathogens most relevant to throat infections and must be firmly swabbed.

A patient requires oxygen via nasal cannula at 2 L/min. The approximate FiO2 (fraction of inspired oxygen) delivered is:

Answer: 28%

At 2 L/min via nasal cannula, the FiO2 is approximately 28%; each liter adds roughly 4% above room air (21%).

Which of the following is the primary purpose of applying a cold compress immediately after an acute musculoskeletal injury?

Answer: Reducing inflammation and decreasing pain

Cold application causes vasoconstriction, which reduces edema, bruising, and pain in the acute phase of injury.

When performing a 12-lead ECG, lead V4 is placed at:

Answer: 5th intercostal space, midclavicular line

V4 is placed at the 5th intercostal space in the midclavicular line, which is a key landmark for precordial lead placement.

Which of the following is a contraindication to the use of a heating pad on a patient?

Answer: Areas with impaired sensation or circulation

Impaired sensation or circulation prevents the patient from detecting excess heat, significantly increasing the risk of burns.

When collecting a stool specimen for occult blood testing (FOBT), the patient should avoid which of the following foods for 3 days before the test?

Answer: Red meat and raw vegetables such as radishes

Red meat and certain raw vegetables (e.g., radishes, turnips) contain peroxidases that can cause false-positive results on guaiac-based FOBT.
