Example Question #21 : Care
Urtica dioica (stinging nettle) leaf is used for all of the following except __________.
Allergic rhinitis
Nutritional support
Psoriasis
Anti-inflammation
Psoriasis
Urtica dioica (stinging nettle) leaf extract contains antagonists of the histamine-1 (H(1)) receptor, thus decreasing symptoms of allergic rhinitis and sinusitis. Nettle leaf extract also contains factors that inhibit mast cell tryptase, preventing degranulation and release of a host of pro-inflammatory mediators that cause the symptoms of hay fevers, and inhibits cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), and hematopoietic prostaglandin D(2) synthase. As a nutritive, nettle leaf is an excellent source of vitamin A, vitamin C, iron, and calcium. Nettle leaf has shown no benefit in treatment of psoriasis, though it may help to correct any underlying nutritional deficits.
Example Question #22 : Care
Which botanical is known for its antiviral/antiretroviral activity?
Hypericum perforatum (St. John's wort)
Crategus spp (hawthorne)
Avena sativa (milky oat seeds)
Melissa officinalis (lemon balm)
Hypericum perforatum (St. John's wort)
Hypericum perforatum (St. John's wort) has shown significant antiviral activity against a wide variety of of enveloped viruses and retroviruses. Melissa officinalis (lemon balm) and avena sativa (milky oat seeds) are both better known for their sedative effects, and crategus spp (hawthorne) is used as an antiarrhythmic and mitigates oxidative stress in cardiomyopathies.
Example Question #23 : Care
What anti-microbial constituent makes Arctostaphylos uva-ursi useful for treating urinary tract infections?
Tannins
None of these; this herb is not used for urinary tract infections
Flavanoids
Hydroquinone glycosides
Hydroquinone glycosides
Uva-ursi contains the hydroquinone glycosides arbutin and methylarbutin, both of which have shown significant antimicrobial effects in the urinary tract. The other constituents listed have no effect on urinary infections.
Example Question #24 : Care
Which of the following homeopathic remedy is indicated for irritable, colicky infants who cry frequently and arch their back and who are only soothed by bouncing or pressure (such as swaddling)?
Calcarea carbonica
Arnica
Arsenicum album
Chamomilla
Chamomilla
Children needing chamomilla are hot, irritable, and very sensitive to pain. Infants are prone to colic and gastroesophageal reflux disease (GERD). They will often arch backwards when crying, and will be soothed when bounced, carried, patted, or swaddled. These infants experience difficult dentition and will chew their fingers before teething.
Arsenicum album and calcarea carbonica are both more often indicated for chilly babies that are prone to anxiety, while arnica is generally given for people who have experienced some sort of dissociative shock from a physical or emotional trauma.
Example Question #25 : Care
What are three good food sources of copper?
Tomatoes, bananas, rice
Sesame seeds, cashews, green leafy vegetables
Grapefruit, pear, bean sprouts
Beef, eggs, apples
Sesame seeds, cashews, green leafy vegetables
Sesame seeds, cashews, and green leafy vegetables have among the highest levels of copper per serving. Other foods high in copper include crimini mushrooms, organ meats, shellfish, and beans. All of the other foods listed are low-copper foods, often recommended for patients with disorders of copper metabolism, such as Wilson's disease.
Example Question #1 : Triage And Priority
The nurse performs triage in the emergency department for a patient with a bee sting. The family reports a history of allergic reactions to bee stings, and the patient complains of difficulty breathing and swelling in his mouth. Which of the following is the priority of the nurse?
Maintain an open airway.
Administer subcutaneous epinephrine.
Obtain a full patient history.
Administer oral diphenhydramine.
Contact the physician.
Maintain an open airway.
Follow the ABC's of nursing priority: airway, breathing, circulation. It is most most important for the nurse to maintain a patent airway, as the symptoms manifested suggest an anaphylactic reaction. Epinephrine may be given after the airway is established. Oral diphenhydramine is usually given for mild allergic reactions. The physician may be contacted later; patient safety is the priority.
