1 Insulin glargine is a long-acting recombinant DNA human insulin used to treat type 1 and type 2 diabetes mellitus. It has 24-hour duration of action and is administered once a day at the same time each day.

The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving theophylline. The nurse monitors the serum theophylline level and concludes that the medication dosage may need to be increased if which value is noted? 1.5 mg/mL (20 mcmol/L) 2.10 mg/mL (40 mcmol/L) 3.15 mg/mL (60 mcmol/L) 4.20 mg/mL (79 mcmol/L)

1 Thetherapeutic concentrationfortheophylline, when used as a bronchodilator to treat asthma, is generally considered to be 5-15 mcg/mL (28-83 micromol/L) for adults, 5-10 mcg/mL (28-55 micromol/L) for children and neonates.Levelsgreater than 20 mcg/mL (111 micromol/L) are consideredtoxic. So with value of 5 mg/mL (20 mcmol/L) indicated that the therapeutic serum range is very low. And thus need to increase dosage

The home care nurse is reviewing the record of a client newly diagnosed with glaucoma who is scheduled for a home visit. The nurse notes that the primary health care provider (PHCP) has prescribed atropine sulfate and pilocarpine hydrochloride eye drops. The nurse should contact the PHCP before the home visit for which reason? 1.Clarify the prescription for the atropine sulfate. 2.Clarify the prescription for the pilocarpine hydrochloride. 3.Determine the date of the scheduled follow-up PHCP visit. 4.Determine the extent of the intraocular pressure caused by the glaucoma.

1. Clarify the prescription for the atropine sulfate.Rationale:Atropine sulfate is a mydriatic and cycloplegic medication that is contraindicated in clients with glaucoma. Mydriatic medications dilate the pupil and cause increased intraocular pressure in the eye. Pilocarpine hydrochloride is a miotic agent used in the treatment of glaucoma. It is unnecessary to contact the HCP regarding the date for follow-up treatment. In fact, the client may know this date, which the nurse can ask about during the home care visit. It is unnecessary to know the extent of the intraocular pressure caused by the glaucoma in planning care for the client.

1. Hypoglycemia may be experienced before dinnertime. 3. The insulin should be administered at room temperature.

The nurse is reviewing the history and physical examination of a client who will be receiving asparaginase, an antineoplastic agent. The nurse contacts the primary health care provider before administering the medication if which disorder is documented in the client's history? 1.Pancreatitis 2.Diabetes mellitus 3.Myocardial infarction 4.Chronic obstructive pulmonary disease

1. Pancreatitis Asparaginase is contraindicated if hypersensitivity exists, in pancreatitis, or if the client has a history of pancreatitis. The medication impairs pancreatic function and pancreatic function tests should be performed before therapy begins and when a week or more has elapsed between dose administrations. The client needs to be monitored for signs of pancreatitis, which include nausea, vomiting, and abdominal painThe conditions noted in options 2, 3, and 4 are not contraindicated with this medication.

The nurse is reviewing the primary health care provider's (PHCP's) prescriptions for a client recently admitted to the hospital and notes that the PHCP has prescribed ticlopidine therapy. Which finding on the client's record would indicate a need to contact the PHCP before initiating the medication prescription? 1.Neutropenia 2.Client history of stroke 3.Client history of hypertension 4.Complaints of gastrointestinal disturbances

1.Neutropenia Rationale:Neutropenia, or agranulocytosis, is the most serious adverse effect associated with the use of ticlopidine. A baseline complete blood cell (CBC) count with differential will be performed for the client. Neutropenia occurs most often within the first 3 months of therapy; therefore, a CBC with differential is recommended every 2 weeks during the first 3 months. If a diagnosis of neutropenia is determined, the client will be withdrawn from therapy. This medication is used to prevent a stroke and is not contraindicated in hypertension. Gastrointestinal disturbances can occur as a result of taking the medication, and the client is instructed to take the medication with food to minimize these side effects.

The nurse is preparing an intravenous (IV) infusion of phenytoin as prescribed by the primary health care provider for the client with seizures.

Which information should the nurse incorporate in the discussion? 1.Consume a low-fiber diet. 2.Increase fluids and bulk in the diet. 3.Rest if the heart begins to beat rapidly. 4.Take antidiarrheal agents if diarrhea occurs.

2 Increase fluids and bulk in the diet Oxazepam causes constipation, and the client is instructed to increase fluid intake and bulk (high fiber) in the diet. If the heart begins to beat fast, the health care provider (HCP) is notified because this could indicate overdose. In addition, diarrhea could indicate an incomplete intestinal obstruction and, if this occurs, the HCP is notified.

The nurse is performing a follow-up teaching session with a client discharged 1 month ago. The client is taking fluoxetine. Which information would be important for the nurse to obtain during this client visit regarding the side and adverse effects of the medication? 1. Cardiovascular symptoms 2. Gastrointestinal dysfunctions 3. Problems with mouth dryness 4. Problems with excessive sweating

2. Gastrointestinal dysfunctionsRationale:The most common adverse effects related to fluoxetine include central nervous system (CNS) and gastrointestinal (GI) system dysfunction. This medication affects the GI system by causing nausea and vomiting, cramping, and diarrhea. Options 1, 3, and 4 are not adverse effects of this medication.

The nurse is caring for a client who is receiving dopamine. Which potential problem is a priority concern for this client? 1.Fluid overload 2.Peripheral vasoconstriction 3.Inability to perform self-care 4.Inability to discriminate hot or cold sensations

A client with diabetes insipidus asks the nurse about the purpose of a new medication, vasopressin. The nurse provides teaching about the medication. Which statement by the client indicates successful teaching? 1."It causes muscle contractions." 2."It opens up my blood vessels." 3."It prevents me from 'peeing' so much." 4."It decreases stomach and colon motility."

3 Diabetes insipidus is an abnormal health condition that occurs due to lack of production of Antidiuretic hormone (ADH) or the inability of the kidney to respond to produced antidiuretic hormone. This can occur as a result of head trauma, tumours of pituitary gland or genetic origin. The common symptoms of Diabetes insipidus includes: --> Excessive production of dilute urine (polyuria) --> Increased thirst (polydipsia). In the management of diabetes insipidus, VASOPRESSIN medication is introduced. It has an antidiuretic effect. In its mechanism of action, it decreases water excretion by the kidney through increasing water reabsorption in the collecting ducts, Therefore the statement made by the patient indicates successful teaching as it helps reduce the volume of urine produced leading to decrease in frequent urination.

A client who has been receiving theophylline by the intravenous (IV) route has the medication prescription changed to an immediate-release oral form of the medication. After discontinuing the IV medication, when should the nurse schedule the first dose of the oral medication? 1.Just after the next meal 2.Just before the next meal 3.4 hours after discontinuing the IV form 4.Immediately on discontinuing the IV form

3 Rationale: 4 hours after discontinuing the IV formWith immediate-release preparations, oral theophylline should be administered 4 to 6 hours after discontinuing the IV form of the medication. If the sustained-release form is used, the first oral dose should be administered immediately on discontinuation of the IV infusion. Therefore the remaining options are incorrect.

"The medication is likely to cause stinging every time it is applied."4. "The medication should be applied directly to the wound."

3. "The medication is likely to cause stinging every time it is applied." Rationale: silver sulfadiazine is an antibacterial that has a broad spectrum of activity against gram-negative bacteria gram positive bacteria, and yeast. It is applied directly to the wound to assistant healing. It does not cause stinging when applied.
