Cystic fibrosis CF is caused by a
Autosomal recessive inheritance
Autosomal dominant inheritance
Infection
Malignancy
The Correct Answer is A
Cystic fibrosis is a genetic disorder caused by mutations in the CFTR gene, which is inherited in an autosomal recessive manner. This means that a child must inherit two copies of the mutated gene (one from each parent) to develop the disorder. If only one parent carries a copy of the mutated gene, their children will not develop cystic fibrosis but may be carriers of the gene.

Correct Answer is C
Explanation
Orthostatic hypotension is a drop in blood pressure that occurs when a person stands up from a sitting or lying down position. To check for orthostatic hypotension, the nurse typically takes the patient's blood pressure and heart rate while the patient is lying down, then has the patient stand up for a few minutes and takes the blood pressure and heart rate again. If the blood pressure drops significantly (usually a drop of 20 mm Hg or more) and the heart rate increases, it may indicate orthostatic hypotension.
Correct Answer is B
Explanation
IgE is the immunoglobulin associated with allergic reactions and is often elevated in patients with asthma. When a person with asthma is exposed to an allergen, their IgE levels increase, leading to the release of inflammatory chemicals such as histamine, which can cause bronchoconstriction and other symptoms of asthma.
IgA: This is an immunoglobulin that plays a role in the immune system's defense against infections. It is mainly found in the mucous membranes of the respiratory and gastrointestinal tracts.
IgG: This is the most abundant immunoglobulin in the bloodstream and plays a role in providing immunity against bacterial and viral infections. It can also cross the placenta and provide passive immunity to a developing fetus.
IgM: This is the first immunoglobulin produced in response to an infection and plays a role in the body's defense against bacterial and viral infections. It is found primarily in the bloodstream.
