The parathyroid hormone controls
Explanation:
The parathyroid gland is responsible for regulating calcium levels in the body. The parathyroid gland secretes parathyroid hormone (PTH), which helps to maintain calcium homeostasis. When calcium levels in the blood are low, the parathyroid gland secretes more PTH, which stimulates calcium release from bones, enhances calcium absorption from the intestines, and reduces calcium excretion by the kidneys. This leads to an increase in calcium levels in the blood. Conversely, when calcium levels in the blood are high, the parathyroid gland secretes less PTH, which inhibits calcium release from bones, reduces calcium absorption from the intestines, and increases calcium excretion by the kidneys. This leads to a decrease in calcium levels in the blood. The regulation of calcium by the parathyroid gland is important for a wide range of physiological processes in the body, including bone formation, muscle contraction, nerve function, and blood clotting.
What instrument has teeth among the ones listed below?

What is the suturing technique used to place brief lateral stitches below the skin's epithelial layer?

Which of the following equipment should be included in a TURP setup?
Explanation:
The resectoscope should be included in a set-up for transurethral resection of the prostate (TURP). The resectoscope is a specialized instrument consisting of a telescope and a wire loop to remove excess prostate tissue through the urethra. The resectoscope allows the surgeon to visualize the prostate and control the wire loop to remove the tissue precisely. Other instruments that may be included in a TURP set-up include a cystoscope for initial visualization of the bladder, a light source, and irrigation fluid.

Which medications can elevate the patient's blood pressure in an emergency?
Explanation:
Epinephrine (Adrenalin) is used in an emergency to raise a patient's blood pressure. It is a potent sympathomimetic drug that stimulates alpha and beta-adrenergic receptors in the body. This leads to increased heart rate, cardiac contractility, and vasoconstriction of blood vessels, which can elevate blood pressure. Epinephrine is often used to treat anaphylaxis, cardiac arrest, and severe hypotension. However, epinephrine must be used with caution, as it can also cause adverse effects such as tachycardia, arrhythmias, and hypertension. A healthcare professional should carefully monitor the dosage and administration of epinephrine.

Which of the following is the strongest against sterilizing techniques?
Explanation:
Spores are the most resistant form of microorganisms to sterilization processes. Bacterial spores are highly resistant to heat, chemicals, and radiation due to their tough outer coating, which makes them difficult to destroy. This is why sterilization of medical instruments and equipment can be challenging, as it requires special techniques and equipment to eliminate bacterial spores. In addition to bacterial spores, prions, abnormal proteins that can cause disease, are also highly resistant to sterilization processes. Proper sterilization is crucial to prevent the spread of infections in healthcare settings, and healthcare professionals must follow strict guidelines and procedures to ensure the safety of patients.
