A nurse is caring for a client who has hyponatremia and is receiving an infusion of a prescribed hypertonic solution.
Which of the following findings should indicate to the nurse that the treatment is effective?

Improved cognition.

Cardiac arrhythmias absent.

Decreased vomiting.

Absent Chvostek’s sign.

Answer and Explanation

The Correct Answer is A

Hyponatremia is a condition where the sodium level in the blood is too low, which can cause confusion, lethargy, seizures, and coma. A hypertonic solution is a fluid that has a higher concentration of solutes than the blood, which can help raise the sodium level and reduce the brain swelling caused by hyponatremia. Therefore, improved cognition indicates that the treatment is effective.

Choice B. Cardiac arrhythmias absent.

Cardiac arrhythmias are not a common symptom of hyponatremia unless it is severe or rapid in onset.

Therefore, their absence does not necessarily indicate that the treatment is effective.

Choice C. Decreased vomiting.

Vomiting can be a cause or a consequence of hyponatremia, depending on the underlying condition.

Decreased vomiting may indicate that the patient is less nauseated, but it does not reflect the sodium level or the brain status.

Choice D. Absent Chvostek’s sign.

Chvostek’s sign is a facial twitching that occurs when tapping on the cheek, which indicates hypocalcemia (low calcium level).

It is not related to hyponatremia or hypertonic solution.

Normal ranges for sodium are 135 to 145 mEq/L and for calcium are 8.5 to 10.5 mg/dL.

Correct Answer is C

Explanation

The correct answer is choice C. Keep the tablets at room temperature in their original glass bottle. Rationales: Choice A rationale: Taking one tablet each morning 30 minutes prior to eating is incorrect. Sublingual nitroglycerin is used to relieve acute angina attacks and is taken as needed rather than on a fixed schedule. Choice B rationale: Discarding any tablets not used every 6 months is incorrect. Sublingual nitroglycerin tablets should be replaced every 6 months to ensure potency, but this is not the main teaching point for safe storage. Choice C rationale: Keeping the tablets at room temperature in their original glass bottle is correct. Nitroglycerin tablets are sensitive to light and moisture, and the original glass bottle protects them from these elements, ensuring their effectiveness. Choice D rationale: Placing the tablet between the cheek and gum to dissolve is incorrect. Sublingual nitroglycerin tablets should be placed under the tongue where they dissolve and are absorbed quickly into the bloodstream for rapid relief of angina symptoms

A. Osteoporosis. B. Deep-vein thrombosis. C. Urinary tract infection. D. Hypothyroidism.

Correct Answer is A

Explanation

Raloxifene is a medication used to prevent and treat osteoporosis in postmenopausal women.

Osteoporosis is a condition that causes bones to become thin and weak, increasing the risk of fractures.

Raloxifene belongs to a class of drugs called selective estrogen receptor modulators (SERMs), which mimic the effects of estrogen on bone density. Choice B is wrong because raloxifene may increase the risk of deep-vein thrombosis (DVT), a type of blood clot that forms in a vein deep in the body. DVT can cause pain, swelling, and redness in the affected limb, and can lead to serious complications such as pulmonary embolism (PE), a blood clot in the lung.

Raloxifene should not be used by people who have or had DVT or PE. Choice C is wrong because raloxifene is not used to treat urinary tract infection (UTI), an infection that affects the bladder, kidneys, or ureters. UTI can cause symptoms such as burning or pain when urinating, frequent or urgent urination, blood in the urine, or fever.

UTI is usually treated with antibiotics.

Choice D is wrong because raloxifene is not used to treat hypothyroidism, a condition that occurs when the thyroid gland does not produce enough thyroid hormone.

Thyroid hormone regulates the body’s metabolism, growth, and development. Hypothyroidism can cause symptoms such as fatigue, weight gain, cold intolerance, dry skin, hair loss, or depression.

Hypothyroidism is usually treated with synthetic thyroid hormone replacement.
