T/F cementum helps to anchor teeth in their sockets.

Answers

Cementum is a specialized calcified tissue that covers the root of the tooth, forming a thin layer over the dentin,the correct answer is True.

Its primary function is to anchor the tooth to the jawbone by attaching the periodontal ligament fibers to the tooth's root surface.

Without cementum, teeth would be unable to remain firmly attached to the socket and would eventually loosen or fall out.

Cementum also serves as a protective layer for the root surface, providing a barrier against external stimuli and bacterial invasion.

It is a unique tissue in that it is formed throughout life, unlike dentin and enamel, which are formed only during tooth development.

Cementum contains various cell types and organic and inorganic components that play a crucial role in tooth support and maintenance.

what drug can be used to control ventricular rate in a patient with atrial fibrillation naplex

Answers

Beta-blockers, such as metoprolol and propranolol, work by blocking the effects of the hormone adrenaline, which can slow down the heart rate and reduce blood pressure.

Calcium channel blockers, such as diltiazem and verapamil, work by blocking the flow of calcium into the heart muscle, which can relax the blood vessels and decrease the heart rate.

Digoxin works by increasing the strength of the heart's contractions and slowing down the rate at which the electrical signals are sent through the heart.

The choice of medication depends on the patient's individual characteristics, such as age, medical history, and comorbidities. In some cases, a combination of medications may be necessary to achieve adequate rate control. Close monitoring of the patient's heart rate and symptoms is essential to ensure the effectiveness and safety of the treatment.

the nurse is caring for a pregnant patient with pregnancy-induced hypertension. when assessing the reflexes in the ankle, the nurse observes rhythmic contractions of the muscle when dorsiflexing the foot. what would the nurse document this finding as?

Answers

The nurse should document this finding as Clonus, which indicates the presence of rhythmic contractions of the muscle when dorsiflexing the foot. It may suggest an increased risk for preeclampsia or eclampsia.

When assessing a pregnant patient with pregnancy-induced hypertension, the nurse is observing the reflexes in the ankle. During the examination, rhythmic contractions of the muscle are noticed when the foot is dorsiflexed. This finding should be documented as clonus. Clonus is a series of involuntary, rhythmic muscle contractions that can occur in various muscles, including those in the ankle. It may indicate hyperreflexia, a heightened responsiveness to stimuli, which is often seen in patients with pregnancy-induced hypertension.

The presence of clonus in a pregnant patient with hypertension is important to note, as it may suggest a potential risk for developing more severe conditions, such as preeclampsia or eclampsia. Preeclampsia is characterized by high blood pressure and damage to organs, while eclampsia involves seizures in addition to preeclampsia symptoms. Proper documentation and reporting of clonus are crucial to ensure appropriate monitoring and timely interventions for the patient's safety.
