A client's Sodium level is 128 meq/L. The nurse knows that a likely cause of this lab finding is:

Deficient intake of protein.

Administration of hypotonic IV fluids.

Excessive dietary intake of salt.

Overdose of supplemental Potassium pills.

Answer and Explanation

The Correct Answer is B

A likely cause of a low sodium level (hyponatremia) of 128 mEq/L is the administration of hypotonic IV fluids. Hypotonic IV fluids have a lower concentration of solutes compared to the body's fluids, which can lead to dilutional hyponatremia. When these fluids are administered, they can cause water to move into the cells, diluting the sodium concentration in the bloodstream.

Correct Answer is B

Explanation

Pernicious anemia is a type of anemia that occurs due to a lack of intrinsic factor, a protein necessary for the absorption of vitamin B12 (cobalamin) in the digestive system. As a result, patients with pernicious anemia are unable to absorb sufficient amounts of vitamin B12 from dietary sources. The treatment for pernicious anemia involves regular administration of cobalamin (B12) injections to bypass the impaired absorption and provide the necessary vitamin B12 directly.

Oral ferrous sulfate tablets are not the appropriate treatment for pernicious anemia. Ferrous sulfate is a form of iron supplement used to treat iron deficiency anemia, which is different from pernicious anemia.

Iron dextran infusions are also not indicated for pernicious anemia. Iron dextran is used for iron replacement therapy in cases of iron deficiency anemia, but it does not address the underlying issue of vitamin B12 deficiency in pernicious anemia.

Routine blood transfusions may be necessary in some cases of pernicious anemia, especially if the patient is severely anemic. However, the primary treatment for pernicious anemia is cobalamin (B12) injections, which provide the necessary vitamin B12 that the patient is unable to absorb.

A. Naloxone (Narcan) B. Dantrolene (Dentrum) C. Furosemide (Lasix) D. Flumazenil (Romazicon) E. Flumazenil (Romazicon)

Correct Answer is B

Explanation

The given observations suggest the occurrence of malignant hyperthermia (MH), a potentially life-threatening reaction to certain medications used during anesthesia. MH is characterized by an increase in heart rate (tachycardia), elevated body temperature (hyperthermia), and muscle rigidity. The primary treatment for MH is the administration of dantrolene, which is a skeletal muscle relaxant that helps to counteract the effects of the reaction.

Naloxone (Narcan) is an opioid receptor antagonist used to reverse the effects of opioid overdose or excessive opioid sedation.

Furosemide (Lasix) is a diuretic used to treat conditions such as edema and high blood pressure.

Flumazenil (Romazicon) is a benzodiazepine receptor antagonist used to reverse the effects of benzodiazepine overdose or excessive sedation.
